Gary Edward Gentry (born October 6, 1946) is an American former right-handed Major League Baseball pitcher.

He came within an out of a complete game in his major league debut, defeating the Montreal Expos in front of 8,608 at Shea Stadium.

Gentry pitched a four-hit, 6–0 shutout against the St. Louis Cardinals[4] to clinch the National League East title for the Mets.

Gentry lasted only into the third inning, however, the Mets were able to mount a comeback that would allow them to sweep the NLCS,[6] and head into the World Series against the Baltimore Orioles.

Gentry, meanwhile, held the mighty Orioles scoreless, pitching into the seventh inning before handing the ball to Nolan Ryan for the save.

Unwilling to part with Gentry, the Mets sent Nolan Ryan to the Angels in one of the most infamous trades in franchise history.

Gentry was traded along with Danny Frisella from the Mets to the Atlanta Braves for Félix Millán and George Stone on November 1, 1972.

After surgery to have bone chips removed from his elbow, Gentry returned to the mound on April 30, 1974, pitching an inning of relief.
