The 2018 Toronto Blue Jays season was the 42nd season of the franchise in the American League East division of Major League Baseball (MLB), and the 28th full season of play (29th overall) at Rogers Centre.
During his end-of-season press conference on October 3, 2017, general manager Ross Atkins confirmed that the Blue Jays would decline their mutual option on José Bautista and allow him to enter free agency. Atkins also announced that the team would retain their entire coaching staff entering 2018. On October 11, the team dismissed their assistant athletic trainer, Mike Frostad, as well as head strength coach Chris Joyner.Darrell Ceciliani, Bo Schultz, and César Valdez were outrighted to the Triple-A Buffalo Bisons on November 1. The following day, Brett Anderson, Darwin Barney, Miguel Montero, and Michael Saunders became free agents. On November 4, José Bautista's $17 million mutual option for the 2018 season was officially declined by the Blue Jays, making him a free agent.Leonel Campos, Taylor Cole, Raffy Lopez, and Luis Santos were outrighted to Triple-A on November 6, and pitcher Taylor Guerrieri was claimed off waivers from the Tampa Bay Rays. Former Blue Jays pitcher Roy Halladay died on November 7, when his ICON A5 amphibious airplane crashed into the Gulf of Mexico near the Tampa Bay area of Florida. He was the only person in the airplane. The Blue Jays organization later announced plans to honour Halladay before their game on Opening Day and throughout the 2018 season, by retiring his number and wearing a black 32 patch on their jerseys for the year.
On November 20, the Blue Jays acquired Gift Ngoepe from the Pittsburgh Pirates, outrighted Chris Rowley and Harold Ramírez, lost Rob Refsnyder on a waiver claim by the Cleveland Indians, and added Conner Greene, Danny Jansen, Reese McGuire, Thomas Pannone, and Rowdy Tellez to the 40-man roster in order to protect them from the Rule 5 draft. The Blue Jays organization experienced a spike in positive tests for performance-enhancing drugs during November. Six players with the Dominican Summer League Blue Jays and one with the Gulf Coast League Blue Jays were suspended after testing positive. The team announced on November 23 that they would begin an internal investigation into the positive reports. Late in the month, it was announced that assistant general manager Andrew Tinnish had been hired by the Atlanta Braves, who had recently hired former Blue Jays general manager Alex Anthopoulos. On December 1, Tinnish announced he had withdrawn from his position with Atlanta and would remain with Toronto. Also on December 1, the Blue Jays non-tendered Ryan Goins and Tom Koehler, and traded minor league outfielder J. B. Woodman to the St. Louis Cardinals for infielder Aledmys Díaz. Head athletic trainer George Poulis, who had been with the Blue Jays organization for 18 years, was hired by the Atlanta Braves on December 5.
On January 6, 2018, the Blue Jays traded Edward Olivares and Jared Carkuff to the San Diego Padres for infielder Yangervis Solarte.Ezequiel Carrera, Josh Donaldson, Dominic Leone, Aaron Loup, Kevin Pillar, Aaron Sanchez, and Devon Travis each avoided salary arbitration with the Blue Jays on January 12, agreeing to one-year contracts. Marcus Stroman and Roberto Osuna were unable to reach agreements with the team prior to the deadline. Dominic Leone and prospect Conner Greene were traded to the St. Louis Cardinals for outfielder Randal Grichuk on January 19.Curtis Granderson's one-year, $5 million contract became official on January 23. MLB revealed their top 100 prospects list on January 27, with Blue Jays prospects Vladimir Guerrero Jr., Bo Bichette, and Anthony Alford ranking 3rd, 14th, and 47th respectively.
Roberto Osuna lost his arbitration case with the Blue Jays on February 3, and was awarded the team's $5.3 million contract instead of his requested $5.8 million.Jerry Howarth, the team's play-by-play announcer, announced his retirement on February 13 after 36 seasons with the Blue Jays. On February 15, Marcus Stroman announced through his Twitter account that he had lost his arbitration case and would make $6.5 million for the season instead of his requested salary of $6.9 million. Later that day, the team announced Jaime García had been signed to a one-year, $8 million contract that included a 2019 team option.

Blue Jays pitchers and catchers reported to spring training on February 14, while position players reported on February 19.Seung-hwan Oh signed a one-year, $2 million contract with Toronto on February 26. To make room on the roster, Ezequiel Carrera was designated for assignment. Carrera later cleared waivers and was invited back to spring training.Nick Tepesch signed a minor league contract with the Blue Jays on March 3, and was invited to spring training. Early in spring training, it was announced that Troy Tulowitzki had a bone spur in his right ankle, and that he would miss the start of the Grapefruit League season. On March 4, manager John Gibbons stated Tulowitzki was unlikely to be ready for Opening Day. Top prospects Vladimir Guerrero Jr. and Bo Bichette made their Grapefruit League debuts on March 8, and combined to go 6-for-8 with two RBIs and three runs scored in Toronto's 9-3 win over the Baltimore Orioles. The Blue Jays made their first cuts of spring training on March 10, optioning Rowdy Tellez to the Triple-A Buffalo Bisons, and sending Jon Harris, Sean Reid-Foley, and Jordan Romano to minor league camp. The following day, Ryan Borucki and Thomas Pannone were optioned to Buffalo, and Ezequiel Carrera was released.
On March 12, Gibbons announced that Marcus Stroman would not start on Opening Day due to shoulder inflammation he suffered early in spring training. Major League Baseball announced an 80-game suspension for Thomas Pannone on March 16, after he tested positive for a banned performance-enhancing substance. On March 20, Gibbons revealed that J. A. Happ would start on Opening Day, and be followed in the five-man rotation by Aaron Sanchez, Marco Estrada, Marcus Stroman, and Jaime García. On March 26 and 27, the Blue Jays returned to Montreal's Olympic Stadium for two games against the St. Louis Cardinals. The team finished spring training with a 14-18 record and one tie.

The Blue Jays opened the 2018 regular season with a four-game series against the New York Yankees. Roy Halladay, who died in the offseason in a plane crash, was honoured before the game and had his number 32 retired by the team. In the first game, Yankees' offseason acquisition Giancarlo Stanton led the way on offence, hitting two home runs in the 6-1 loss for Toronto.Masahiro Tanaka held the Toronto offence at bay in game two, yielding just a single run in six innings as the Jays fell 4-2. Toronto earned their first win of the 2018 season in the third game, 5-3. Yangervis Solarte hit the go-ahead home run in the eighth inning, before Kevin Pillar added an insurance run by stealing home, after having singled and stolen both second and third base. The Blue Jays split the series with a 7-4 win on April 1, thanks to Justin Smoak's grand slam in the eighth inning. The team then began a three-game series against the Chicago White Sox. Russell Martin's first home run of the season gave the Jays the lead in the seventh inning, and Roberto Osuna earned his second save of the year in the 4-2 victory. A seven-run eighth inning by the Jays in the second game led to a 14-5 rout of Chicago. The Blue Jays were denied their first sweep of the season, after José Abreu's go-ahead solo home run gave the White Sox a 4-3 win.
The Blue Jays opened their 2018 road play in Arlington for three games against the Texas Rangers. The Jays took an 8-0 lead in the sixth inning of the first game, and held on to win 8-5. The Rangers took the second game, 5-1, with Rangers starter Mike Minor earning his first win as a starting pitcher since the 2014 season. In the rubber match, Rangers ace Cole Hamels allowed two first-inning home runs, and Toronto took the series with a 7-4 victory. The Jays then made their first trip to Camden Yards to take on the Baltimore Orioles. Josh Donaldson's late-game grand slam gave the Blue Jays a 7-1 win. The game's paid attendance of 7,915 was the lowest in Orioles history, aside from the game played to an empty stadium during the 2015 riots. Aaron Sanchez took a no-hitter into the seventh inning of the second game, as the Jays edged the Orioles 2-1 thanks to a late home run by Curtis Granderson. Baltimore took the final game of the series, 5-3. To close the season's first road trip, the Blue Jays traveled to Cleveland, to take on the Indians. Prior to the first game, Toronto placed Josh Donaldson on the disabled list. The Jays went down 4-0 through two innings in the first game, before scoring eight unanswered runs to take the game 8-4. The other two scheduled games of the series were rained out, and postponed to May 3 for a doubleheader.
Returning home for a brief, three-game series against the Kansas City Royals, the Blue Jays experienced just their second postponement since moving to the Rogers Centre in 1989. A section of ice, formed during a weekend freezing rain storm, fell from the CN Tower and pierced the roof of the stadium, forcing the team to schedule a doubleheader for the following day due to safety concerns. A six-run sixth inning in the first game cemented the win for the Jays, while backup catcher Luke Maile's walk-off single in the tenth inning of the second game gave Toronto the rare home doubleheader sweep, by scores of 11-3 and 5-4. The Blue Jays would complete the series sweep with a 15-5 win on April 18, led by Curtis Granderson's ninth-career grand slam. The team then returned to the road for four games against the Yankees. They would split the first two games of the series, with the Yankees winning the first 4-3 and the Jays taking the second 8-5. New York would hold the Blue Jays to a single run in each of the next two games, taking the series with 9-1 and 5-1 victories.
The Blue Jays struggled through a generally mediocre month of May. Reasons for their struggles throughout the month were generally attributed to the Blue Jays having lost Osuna to administrative leave following accusations of domestic violence, the suspension of Osuna for 75 games for that offence, and injuries to several key players such as Josh Donaldson. For the first time since the month of May 1979, the team failed to win back-to-back games for the entire month.
The team posted their lowest monthly winning percentage of the season in the month of May (.322) after winning just nine games while losing nineteen. A significant detriment to the team's record was being swept twice during the month, first by the Boston Red Sox and then the Oakland Athletics, which added seven losses without any wins. The Blue Jays began their season with a three-game series against the Minnesota Twins at their home stadium, Rogers Centre, which they won two games to one behind their strong offensive performance, scoring fourteen runs over the series. The team travelled to face the Cleveland Indians in two make-up games, which were postponed after rain and inclement weather forced a postponement of the games that were originally scheduled for April 14th and April 15th. They won the first game in extra innings 13-11 after they scored four runs in the eleventh inning, but lost the second game 4-13 after the Indians were able to score nine runs in a single inning.
Over each of the next three consecutive three-game series, where they played against Tampa Bay Rays, Seattle Mariners, and Boston Red Sox, the Blue Jays posted the same losing record of 1-2. In the first series against Tampa Bay at Tropicana Field, they lost the first two games by a combined five runs to eleven behind a strong pitching performance from the Rays. They won the third and final game of the series 2-1, only after a wild pitch in the ninth inning allowed the winning run to score. After having their first day off in two full weeks, the Blue Jays returned home to face the Mariners in a three-game series. They lost the first game 0-5, after pitcher James Paxton, a Canada native, threw a no-hitter to leave the Blue Jays without a hit or run over nine innings. They would win the next game 5-2, as the team got twelve hits to the Rays' five; however, on the next night, the Rays would get seventeen hits to the Blue Jays' eight in a 3-9 loss. The Blue Jays remained at home to play the Red Sox in a three-game series. They won the first game 5-3 in extra innings, as catcher Luke Maile hit two home runs, one to tie the game in the seventh inning, and one to win the game in the bottom of the twelfth inning. However, the team would lose the next two games behind strong pitching and hitting performances from the Red Sox.
After playing the last two series at home, the Blue Jays travelled to Citi Field to play the New York Mets in a two-game series. They lost the first game 2-12 behind a strong pitching and hitting performance from the Mets' starting pitcher, Noah Syndergaard. However, they won the second game 12-1 as the team got fifteen hits, and their starting pitcher, J.A. Happ, only allowed two hits while striking out ten batters over seven innings. This would be the first time the Blue Jays would win against the Mets in an road game in franchise history. After their series against the Mets, the Blue Jays returned home to Rogers Centre to play a four-game series against the Oakland Athletics. Despite both teams having an even 22-22 record following the first game in the series, the Athletics would go on to sweep the Blue Jays. The team was limited to twelve total runs over the four losses, compared to the Athletics' twenty-seven. This would be the second time, and not the last, that the team would lose four straight games in the 2018 season. After a day off, the Blue Jays remained at home to play a three-game series against the Los Angeles Angels. They snapped their four-game losing streak with a 5-3 win in the first game, where they scored all five runs in the first inning. However, they would go on to lose the next two games and the series. They were up 3-0 in the bottom of the fifth inning, but after the Angels scored four runs in the top of the ninth inning, the Blue Jays ended up losing 4-5. They would also lose the last game 1-8 behind a robust offensive performance from the Angels.
After losing eight of their last ten games, the Blue Jays travelled to Citizens Bank Park to play the Philadelphia Phillies in a three-game series. They won the first game 6-5 as the Blue Jays' bullpen held on to win a game that the team was winning 6-1 in the bottom of the fifth inning. However, the team would go on to lose the next game 1-2 after two short rain delays and a strong pitching performance from the Phillies' starter Aaron Nola. Behind an eight-strikeout pitching performance from their starter J.A. Happ, the Blue Jays won the final game of the series 5-3. This would be the first time in a month that the team would win a series. To complete a rather mediocre month of May, the Blue Jays would get swept by the Boston Red Sox in a three-game series at Fenway Park. They lost both the first and the second game 3-8, as the Red Sox offense was lethal throughout both games. They lost the final game in the series 4-6 to complete the sweep for Boston, as Red Sox outfielder J.D. Martinez hit his league-tying eighteenth home run. By the end of an unexceptional month of May, the Blue Jays would have a subpar 25-31 overall record, and would be fourteen games behind the first-place Boston Red Sox in the American League East Division.
Coming off a below-average month of May, the Blue Jays would look to improve on their 25-31 overall record. Although they would lose the first two games in the month of June to the Detroit Tigers, the Blue Jays would go on to win fourteen games in June while losing twelve. June would be the last month of the regular season where the Blue Jays would post a winning record, and the only such month other than April, when the team posted a 15-10 record. In the first series of the month, the Blue Jays travelled to Comerica Park to play three games against the Detroit Tigers. They would lose the first two games as the Detroit offense scored twelve combined runs to the Blue Jays' seven. They would win the next game 8-4 behind a strong performance by their starting pitcher Aaron Sanchez, breaking a five-game losing streak dating back to late May. After a day off, the Blue Jays returned home to play the New York Yankees at the Rogers Centre in a two-game series. They would lose both games after the high-powered offense of the Yankees put up ten combined runs to the Blue Jays' two. This would not be the last time that the Blue Jays were swept in a series or shutout in a game during the month of June.
After losing eight out of their last ten games, the Blue Jays would go on to sweep the Baltimore Orioles in a four-game series at home, their first time being on the positive side of a sweep since the middle of April. They outscored the Orioles by a combined twenty-seven runs to eleven, including a thirteen-run win in the fourth and final game of the series. After winning their last four games, the Blue Jays would travel to Tropicana Field to play a three-game series against the Tampa Bay Rays. In their second series against the Rays this season, the Blue Jays would get swept, including a 1-0 shutout in the third and final game. After a day off to return home to Rogers Centre, the Blue Jays would face the Washington Nationals in a three-game series. They would go on to sweep the Nationals in three games, the second of which was as 2-0 shutout, behind strong offensive performances by their starting infielder Yangervis Solarte. After winning seven of their last ten games, the Blue Jays faced the Atlanta Braves in a two-game series at home. They lost the first game 4-11, as the Braves got fourteen hits while hitting two home runs; they would go on to win the second game 5-4 behind a strong performance from their starting pitcher J.A. Happ, who struck out eight batters over 8 1/3 innings.
The Blue Jays then travelled to Angel Stadium to face the Los Angeles Angels in a four-game series. The team would lose the first two games, 8-5 and 2-1, despite getting more tying or beating the Angels in hits both games. They would go on to win the next game 4-1, after scoring three runs in the top of the ninth inning. They would also win the following game 7-6 in extra innings, as designated hitter Kendrys Morales hit a pinch-hit home run in the top of the tenth inning. The Blue Jays then travelled to Minute Maid Park to face the Houston Astros in a three-game series. The team would win the first game 6-3, as starting outfielder Curtis Granderson hit two home runs. They would then go on to lose the next two games, the first of which was a 0-7 shutout behind a dominant performance from Astros' starting pitcher Charlie Morton, and the second of which was a 6-7 loss as Astros' starting infielder Alex Bregman hit a two-run walk-off home run to seal the comeback win. The final series of the month of June for the Blue Jays would be a four-game series against the Detroit Tigers at Rogers Centre. As the Blue Jays began the month with two losses to the Tigers, they ended the month with two wins against them. They won the first game 3-2 behind a stellar seven-inning performance from their starting pitcher Marcus Stroman. In their last final game of the month of June, the team won 4-3 as starting first baseman Justin Smoak hit a walk-off home run in the bottom of the ninth inning to seal the win. By the end of an adequate month of June, the Blue Jays would have a below-average 39-43 overall record, and would be sixteen games behind the first-place Boston Red Sox in the American League East Division.
After a competent month of June where the team posted a 14-12 record, the Blue Jays would only worsen their 39-43 overall record. The team would post an abysmal 9-15 record in July, their second-worst winning percentage by month (.375), only after May. They would begin by the month by losing their first two games, which were the final two games of a four-game series at home with the Detroit Tigers that began in late June. They would lose by a combined 12-3 after a strong offensive performance from the Tigers' starting outfielder Nicholas Castellanos in the first game, and an exceptional eight-inning performance from the Tigers' starting pitcher Mike Fiers in the second game. The Blue Jays would then play the New York Mets in Rogers Centre in two-game series. They would win the first game 8-6, but then lose the next one 3-6. After a day off, the Blue Jays played the New York Yankees in a three-game series at home. They would win the first game 6-2 as starting first baseman Justin Smoak hit a three-run home run early, but would then lose the next two 5-8 and 1-2, respectively.
After playing three consecutive home series, the Blue Jays travelled to SunTrust Park to play the Atlanta Braves in a two-game series. The team would win the first game 6-2 as starting pitcher Marcus Stroman pitched six innings while only allowing one run. They would lose the second game 5-9 as the Braves scored six runs by the end of the second inning. The Blue Jays then travelled to Fenway Park to play the Boston Red Sox in a four-game series. The team would get its lone win in the series in the second game as they won 13-7, but would lose the other three games by a combined seventeen runs to eight. After a four-day break for the MLB Home Run Derby and All-Star Game, which only included one selection from the Blue Jays (J.A. Happ) and symbolically marks the halfway point in the regular season, the Blue Jays faced the Baltimore Orioles in a three-game series at Rogers Centre. Similarly to the last time the team played the Orioles in a series, the Blue Jays completed the sweep. They beat the Orioles in three close games, 8-7, 4-1, and 5-4.
Looking to improve on their three-game win streak, the Blue Jays faced the Minnesota Twins in a three-game series at home. The team would go on to lose their next three games, as the Twins completed the sweep. The second game was a 0-5 shutout as Twins' starting pitcher Jose Berrios threw seven scoreless innings with nine strikeouts. After a day off, the Blue Jays travelled to Guaranteed Rate Field to play the Chicago White Sox in a three-game series. The Blue Jays would win the series two games to one, which would be the second and last winning series for the team in the month of July. The month of July would end in a similar way as it began for the Blue Jays, as they lost their final two games by a combined sixteen runs to three in a three-game series against the Oakland Athletics. By the end of a mediocre month of July, the Blue Jays would have a subpar 48-58 overall record, and would be a dispiriting 25 1/2 games behind the first-place Boston Red Sox in the American League East Division.
After an inadequate month of July where the Blue Jays won only nine of their twenty-four games, the team would only perform slightly better in August. They would post a 13-15 record for the month, winning four more games than the previous month but still losing more than winning. The first game of August would be the third and final game of a three-game series against the Oakland Athletics that began in late July. The Blue Jays lost 3-8, and the Athletics were able to sweep to Blue Jays for the second time this season. The Blue Jays then travelled to T-Mobile Park to face the Seattle Mariners in a four-game series. After a three-game losing streak, the team won the next three games by a combined 19-6 to win the series, but then lost the fourth and final game 3-6. After three consecutive road series, the Blue Jays returned home to Rogers Centre to play the Boston Red Sox in a three-game series. They lost the first two games, as the Red Sox posted ten runs in both games while the Blue Jays scored seven and five, respectively, but then won the third and final game of the series 8-5. The team then faced the Tampa Bay Rays in a three-game series, but ended up losing the series two games to one as they only scored five runs to the Rays' ten. They lost the first game as they were shutout 0-7, but won the third and final game 2-1.
After playing six games at home, the Blue Jays travelled to Kauffman Stadium to face the Kansas City Royals in a four-game series. They lost the first game 1-3 as Royals' starting pitcher Brad Keller threw seven innings only allowing one run. They won the next two games by the same score, 6-5. The team lost the fourth and final game of the series 2-6, as they scored two runs in the first four innings and did not score again. They then travelled to Yankee Stadium to play a three-game series against the New York Yankees. The Blue Jays were swept as the Yankees offense remained strong throughout the series, scoring twenty-eight runs to the Blue Jays' thirteen. In the final game, J.A. Happ received the win as starting pitcher for the Yankees against his former team, as he was traded from the Blue Jays to the Yankees for an infielder Brandon Drury and outfielder Billy McKinney in the previous month. After being on the negative side of a sweep, the Blue Jays would go on to sweep the Baltimore Orioles in a three-game series at home at Rogers Centre. They outscored the Orioles by a combined nineteen runs to five, including a shutout in the third and final game of the series.
The Blue Jays looked to improve on their three-game win streak as they faced the Philadelphia Phillies in a three-game series at home. They would win the first two games, 4-2 and 8-6, respectively, and extend their win streak to five games, but would go on to lose the third and final game of the series, 3-8. The team then travelled to Oriole Park to play the Baltimores Orioles in a three-game series. Only a week after the Blue Jays' last series against the Orioles where they completed the sweep, the Blue Jays were on the losing side of a sweep, as they lost their next three consecutive games to the Orioles. The first game of the series was a 0-7 shutout; the Orioles did not score fewer than seven runs in any of the three games. After a day off, the team travelled to Marlins Park to face the Miami Marlins in a three-game series. The final game of August for the Blue Jays was a 6-5 win against the Marlins to start the series, as the Blue Jays scored five runs in the top of the ninth inning to complete the comeback. By the end of a disappointing month of August, the Blue Jays would have a below-average 61-73 overall record, and would be a discouraging 31 games behind the first-place Boston Red Sox in the American League East Division.
After an insufficient month of August, as the Blue Jays were swept twice and won thirteen games out of a possible twenty-eight, the team's hopes for making the postseason were in jeopardy as the final month of the regular season began. The team would perform worse in September than they did in the previous month, as they would post a 12-16 record for the month, and be eliminated from playoff contention in early September. The first two games of the month of September were the final two games of a three-game series against the Miami Marlins that had begun the previous day in August. The Blue Jays would lose the second game of the series 3-6, but win the third game 6-1, as starting pitcher Sean Reid-Foley pitched seven innings with ten strikeouts. The Blue Jays then returned home to Rogers Centre to play the Tampa Bay Rays in a three-game series. Although they lost the first two games, by a score of 1-7 and 0-4, respectively, they won the third and final game of the series 10-3, after scoring seven runs in the bottom of the first inning.
The Blue Jays remained at home to play a four-game series against the Cleveland Indians. They alternated games with the Indians, losing the first 4-9, winning the second 3-2, losing the third 8-9, and winning the final game 6-2. Following the 8-9 loss in the third game of the series, the Blue Jays were mathematically eliminated from playoff contention. After a day off, the team travelled to Fenway Park to face the Boston Red Sox in a three-game series. For the ninth and final time, the Blue Jays were swept. The Red Sox outscored the Blue Jays twelve runs to five during the three-game series. After losing to the best team in their division in the Red Sox, the Blue Jays travelled to Yankee Stadium to play a three-game series against the second-best team in the American League East, the New York Yankees. They would be shutout in the first game 0-11, but would win the final two games 8-7 and 3-2, respectively. The team would then travel to Orioles Park to play the Baltimore Orioles in a three-game series. They would shutout the Orioles in the first game 5-0, win the second game 6-4, and lose 1-2 in the final game of the series.
After playing three consecutive three-game series on the road, the Blue Jays returned home to Rogers Centre to play a four-game series against the Tampa Bay Rays. They would alternate games with the Rays, winning the first game 9-8, losing the second 3-11, winning the third 5-2, and losing the final game 2-5. For their final home series of the regular season, the Blue Jays played the Houston Astros in a three-game series. They would lose the first two games, 3-5 and 1-4, respectively, but would win their final home game of the regular season 3-1. For their final series of the regular season, the Blue Jays travelled to Tropicana Field to face the Tampa Bay Rays in a three-game series to complete the regular season. This series would mark the third meeting of these teams in the month of September, and the final game for both teams for the 2018 season, as neither team would reach the postseason. The Blue Jays would receive their final win of the season in the first game of the series, as they won 7-6. They would go on to lose the final two games of the series, and the season, 3-4 and 4-9, respectively.
By the end of the month of September, the MLB regular season ended, and the season formally concluded for the Blue Jays. The team finished with a below-average 73-89 overall record, did not reach the postseason, and were 35 games behind the Boston Red Sox, who would go on to win the American League East division title, and the 2018 World Series championship.
