Daniel Thomas Plesac (born February 4, 1962 in Gary, Indiana) is a former Major League Baseball pitcher with an 18-year career from 1986 to 2003. He played for the Milwaukee Brewers, Toronto Blue Jays, Chicago Cubs, Pittsburgh Pirates, Arizona Diamondbacks, and Philadelphia Phillies.
A hard thrower with a mid-90 MPH fastball and a nasty slider, Plesac was originally a starting pitcher before becoming the closer of the Milwaukee Brewers. Plesac served primarily as a left-handed specialist from the mid-1990s until the end of his career, pitching for the Blue Jays twice, the Diamondbacks, and the Phillies.
He was elected to the American League All-Star team three times (1987, 1988 and 1989). He ended with a 65-71 record and a 3.64 ERA in 1,064 games and 1,072 innings pitched.
