John David Weathers (born September 25, 1969 in Lawrenceburg, Tennessee) is a Major League Baseball pitcher for the Milwaukee Brewers. He bats and throws right-handed. He attended Motlow State Community College in Moore County, Tennessee and was drafted by the Toronto Blue Jays in the 3rd round of the 1988 major league baseball draft. Weathers made his major league debut with the Blue Jays on August 2, 1991, and was drafted by the Florida Marlins in the 1992 MLB expansion draft. Weathers played for the Marlins until 1996, when he was traded to the New York Yankees for Mark Hutton. Weathers won a World Series ring with the Yankees that year.
Weathers is one of only three active MLB players who played for the Marlins during their 1993 inaugural season (the others are fellow relief pitcher Trevor Hoffman and Gary Sheffield).
On December 20, 1997, he was claimed off waivers by the Cincinnati Reds. On June 24, 1998, Weathers was claimed off waivers by the Milwaukee Brewers. Weathers stayed with Milwaukee until July 30, 2001, when he was traded to the Chicago Cubs, along with Robert Miniel, for Ruben Quevedo and Pete Zoccolillo. He became a free agent at the end of the season and signed with the New York Mets. Weathers pitched for the Mets until June 17, 2004, when he and Jeremy Griffiths were traded to the Houston Astros for Richard Hidalgo. Weathers was released by the Astros on September 7, 2004, and signed with the Marlins the very next day.
