Leonard Matarazzo (September 12, 1928 – June 19, 2015) was an American professional baseball player. On September 6, 1952, the right-handed pitcher appeared in the Major Leagues for the only time. Pitching for the Philadelphia Athletics, he worked one scoreless inning in relief against the Boston Red Sox. But he was not given another opportunity to pitch that year and spent the final two seasons of his six-year pro career in the minor leagues. Matarrazo was sent back to Fayetteville for the 1953 season, and retired after the 1954 campaign.
