Cubs 6, White Sox 3
Carlos Pena's three-run homer keyed a four-run sixth inning as the visiting Chicago Cubs came back for a 6-3 victory over the Chicago White Sox on Monday.
Starlin Castro led off the sixth with a game-tying solo home run to left against Gavin Floyd (6-7), who allowed the next two Cubs to reach base before Pena ripped a 3-2 pitch over the wall in right center.
Carlos Zambrano (6-4) allowed seven hits, two walks and struck out five in eight innings, and Carlos Marmol worked the ninth for his 15th save.
The White Sox took a 3-0 lead in the first on a two-run homer by Paul Konerko and an RBI single by Carlos Quentin.
Castro got the Cubs on the board with a two-run single in the third.
White Sox manager Ozzie Guillen was ejected in the bottom of the sixth for arguing balls and strikes.
