Wes Avi Littleton (born September 2, 1982 in Hayward, California) is a right-handed Major League Baseball relief pitcher for the Boston Red Sox. Littleton, who pitches with a sidearm delivery, made his major league debut on July 4, 2006 in a game against the Toronto Blue Jays.
He was credited with saving the game between the Rangers and the Baltimore Orioles on August 22, 2007 -- a game in which Littleton pitched the final three scoreless innings in relief, after entering the game with a 14-3 lead and keeping the lead while his team scored another 16 runs. The award of a save in that situation is consistent with baseball rules. In addition, it was one of the longest outings for a save that year, and the 30 runs scored by the Rangers in the 30-3 win was the most runs scored by one team in a game since 1897. On November 28, 2008, Littleton was traded to the Boston Red Sox in exchange for a player to be named later, later determined to be minor league pitcher Beau Vaughan.
