Jerry Dean Hinsley (born April 9, 1945) is an American former professional baseball player, a right-handed pitcher whose career extended from 1963 through 1971. He had two trials in Major League Baseball for the 1964 and 1967 New York Mets. Hinsley stood 5 feet 11 inches (1.80 m) tall and weighed 165 pounds (75 kg), and originally signed with the Pittsburgh Pirates in 1963 out of high school in Las Cruces, New Mexico.
He spent the entire 1963 season on the roster of the Pirates' Rookie-level Appalachian League affiliate but did not appear in any games. He was then selected by the Mets in the Rule 5 draft on December 2. Hinsley began the 1964 season on the Mets' roster and made his debut in professional baseball in the Majors on April 18 against his old organization, the Pirates, in relief. He gave up five hits and two earned runs (coming from a two-run triple by future Hall of Famer Roberto Clemente) in two innings. He made his first start on May 10 against the St. Louis Cardinals at Shea Stadium and lasted 2 2/3 innings, yielding four runs and absorbing his first MLB loss. He appeared in seven more games before being sent to the Triple-A International League for the balance of 1964. Apart from a two-game trial at the end of the 1967 season, Hinsley spent the remainder of his career in minor league baseball.
