Kelly Douglas Wunsch (born July 12, 1972) is an American former Major League Baseball (MLB) pitcher who played for the Chicago White Sox and Los Angeles Dodgers from 2000 to 2005.

During his struggles, Wunsch switched to a sidearm style delivery, which gave him better control, but decreased his velocity, forcing him to make the move to being a relief pitcher, instead of a power starter.

Wunsch would go onto make a league-leading 83 appearances out of the bullpen for the White Sox in 2000, pitching to a 6–3 record with 2.93 ERA and 1 save in 61+1⁄3 innings.

[3] The next three seasons, Wunsch was used as a left-handed specialist out of the White Sox bullpen, appearing in 126 games, pitching to 3.00 ERA in 90 innings.

Wunsch began the 2004 season with the White Sox's Triple-A affiliate in Charlotte, while recovering from left shoulder inflammation.
