Only 5-foot, 6-inches, Rotblatt was a Chicago kid who made it big in his hometown for a short time. After an outstanding college career at Illinois, Rotblatt received many offers before signing with the White Sox. He made his big league debut at the age of 20 in 1948, pitching two scoreless innings. After a couple of more years in the minors, Rotblatt earned a spot on the White Sox staff in 1951. Despite winning the second game of the season as a starter, Rotblatt worked out of the bullpen. He compiled a 4-2 mark with a 3.40 ERA in 24 games. Unfortunately, Rotblatt never pitched again in the big leagues after 1951. However, he remained a presence on the Chicago baseball scene until his death in 2013.
