Michael Robert Sirotka (born May 13, 1971, in Houston, Texas) is a former Major League Baseball left-handed pitcher. He is an alumnus of Louisiana State University.
Drafted by the Chicago White Sox in the 15th round of the 1993 Major League Baseball Draft, Sirotka played all six years of his Major League Baseball career for that team. After the 2000 season, he was traded to the Toronto Blue Jays with Kevin Beirne and Brian Simmons for Matt DeWitt and David Wells in a deal that would infamously become labeled by White Sox General Manager Kenny Williams as "Shouldergate", as Sirotka would never pitch again, labeled "damaged goods" by then-Toronto GM Gord Ash. Ash believed that Williams did not turn over all information pertaining to Sirotka's shoulder. Ash later appealed the trade to MLB Commissioner Bud Selig, but Selig refused to overturn the trade.
