Frank MacCormack

Frank Louis MacCormack (born September 21, 1954) is an American former Major League Baseball (MLB) pitcher for the Detroit Tigers and Seattle Mariners .

MacCormack was raised in Secaucus, New Jersey, and played baseball at Weehawken High School, graduating in 1971. He then attended Rutgers University but was rejected as a walk-on for the Scarlet Knights baseball team. He signed with the Tigers in 1973 while pitching for a semi-pro team.

MacCormack reached the majors in June 1976, with an 0–5 record and 5.79 earned run average for the Tigers in eight starts and one relief appearance. He threw a 96 mile per hour fastball in his debut. The Mariners selected him in the 1976 MLB expansion draft.

MacCormack began Seattle's inaugural season in the starting rotation but was sent down to the minors to work on his command. He would never return to the majors, with Seattle releasing him in March 1979.
