John Kruk is a former professional first baseman and outfielder. He played college baseball at Allegany Community College, where Kruk played for Junior College Hall of Fame Coach Steve Bazarnic.

Kruk was the first Major Leaguer to come out of Allegany and has been followed by four others (Stan Belinda, Steve Kline, Joe Beimel and Scott Seabol). Kruk played in the MLB for the San Diego Padres, Philadelphia Phillies, and Chicago White Sox from 1986 through 1995. During his career, he was a three-time MLB All-Star. Kruk's breakout year was 1987 with the Padres. He hit .313 with 20 home runs and 91 RBI, and stole 18 bases, showing surprising speed for someone of his build, although he was caught ten times. After being dealt to the Phillies, Kruk blossomed into an All-Star as the team used him primarily at first base. Kruk played in the All-Star Game in 1991, 1992, and 1993.

After retiring as a player, Kruk became a baseball analyst for ESPN. As of 2021, he is now a color commentator for Phillies' games on NBC Sports Philadelphia.
