Mitch Williams, American baseball player and sportscaster
Mitchell Steven Williams (born November 17, 1964), nicknamed "Wild Thing", is a former relief pitcher in Major League Baseball who played for six teams from 1986 to 1997. He was also a studio analyst for the MLB Network from 2009 to 2014.

Williams, a left-hander with a high-90s fastball and major control issues, was largely effective, especially in the early part of his career earning 192 saves in his 11 seasons including a career high of 43 in 1993. He gave up a walk-off home run to Joe Carter of the Toronto Blue Jays in the sixth game of the 1993 World Series, which gave Toronto a World Series championship win over the Phillies. Williams' career went into decline afterward, although he played in parts of three more major league seasons.
