Korey Lee was 3-for-3 with an RBI and four Chicago pitchers combined on a shutout as the White Sox beat the visiting Washington Nationals 2-0 on Wednesday afternoon in the rubber game of a three-game series. The White Sox have won eight of their past 12 games and their second straight series. After Monday's series opener was postponed by rain, the Nationals and White Sox split a doubleheader Tuesday.
