Stephen Charles "Flip" Filipowicz (June 28, 1921 – February 21, 1975) was a professional American football and baseball player. Filipowicz and Olympic great Jim Thorpe share the distinction of being the only two men to have played for the New York Giants of both baseball and football.
Filipowicz, a fullback and quarterback who played at Fordham University from 1941 to 1943, was drafted by the New York Giants in the first round in the 1943 NFL Draft. Although an undersized back at 5'8", 198 lbs, he was still taken with the sixth overall pick. In his first season, he rushed for 142 yards on 53 attempts and 49 receiving yards. He also attempted two incomplete passes. In 1946 he made seven receptions for 84 yards as well as four interceptions. He retired after the season to become head football, basketball, and baseball coach at Mount Saint Mary's University. He resigned the following year to play baseball.
