Anthony Rizzo hit a two-run homer and Alfonso Soriano added a solo shot to power the Cubs to a 6-2 win over the Rangers. Welington Castillo went 4-for-4 and Luis Valbuena had two hits and drove in two runs for Chicago. The Cubs earned a split of the rain-shortened, two-game set at soggy Wrigley Field. Carlos Villanueva pitched seven innings of two-run ball for the win. The Cubs start a three-game road series with Milwaukee tonight.
