Gary Gentry (born October 6, 1946 in Phoenix, Arizona) is a former right-handed pitcher in Major League Baseball who played 7 seasons for the New York Mets and Atlanta Braves between 1969 and 1975.
Gentry went to Arizona State University, and began his pro baseball career at age 23 in 1969. As a rookie, he won 13 games pitching in a rotation with Tom Seaver and Jerry Koosman. He won a World Series with the Mets that year as the Mets defeated the Baltimore Orioles. He was the winning pitcher in Game 3, which was highlighted by Tommie Agee's two spectacular catches that prevented six Oriole runs. His November 1972 trade to Atlanta was followed by a ruinous elbow injury. He played his last game for the Braves on May 6, 1975 and was re-signed by the Mets, but was released on June 19. During his 7-year career, his pitching record was 46 wins and 49 losses.
