After spending 5 seasons in the Houston Astros minor league system, the Mets acquired Gary Rajsich prior to the 1981 season. Rajsich was immediately assigned to the Mets top minor league team, the Tidewater Tides, where he spent the entire 1981 season hitting 24 home runs in just 253 at bats. Based on his strong 81 season Gary Rajsich made the New York Mets roster out of Spring Training in 1982. He made his debut on April 9th as a pinch hitter for pitcher Jesse Orosco and grounded out to the pitcher. He would spend the entire season with the Mets as a part time outfielder and pinch hitter, but it became obvious early on that though he excelled in the minors his skills would not transfer to the Major League level. He hit .259 with 2 home runs and 12 RBIs. The highlight of his season came on May 18th against the Cincinnati Reds when he hit a 3-run homer, his first in the majors, to give the Mets a 7-1 lead in a game they would win 7-4.
Gary Rajsich returned to Tidewater in 1983 where he hit 28 home runs, good enough to get himself a September call up. He appeared in 11 games filling in for a banged-up Keith Hernandez at first base and hit .333 (12 for 36) with a homer and 3 RBIs.
Prior to the 1984 season the Mets sold his contract to the St Louis Cardinals. He played in a handful of games for the Cardinals before moving on to the San Francisco Giants in 1985. After the 85 season, he played 3 seasons in Japan for the Chunichi Dragons before retiring as a player.
In 91 games for the Mets Rajsich hit .273 with 3 home runs and 15 RBIs.
