Jerry Wayne Hairston, Jr. (born May 29, 1976 in Des Moines, Iowa) is an American professional baseball utility player for the Washington Nationals.
Hairston was drafted in the 11th round of the 1997 Major League Baseball Draft by the Baltimore Orioles, and made his major league debut with the Orioles on September 11, 1998. In his seven seasons with Baltimore, he played in 558 games, batting .261.
He was traded (along with Oriole prospects Mike Fontenot and David Crouthers) to the Chicago Cubs in the 2005 offseason for Sammy Sosa. The Cubs attempted to use Hairston as a leadoff man, but he finished the 2005 season with an unremarkable on-base percentage of .336 and stole only 8 bases in 17 attempts. Even though most Cubs fans initially welcomed the dismissal of Sosa—whose performance was on the decline and was seen as a problematic teammate—the poor play of Hairston would eventually cause many fans to sour on this particular trade.
