Valbuena homered twice against Rockies lefty Chris Rusin in the Astros' win over Colorado on Tuesday afternoon. Entering play Tuesday, Valbuena had hit just two of his 14 homers this season against lefties. With four homers over his last five games, Valbunea has provided cheap power for owners that have stuck with him after a 15-game slump in late May and early June where he hit .094/.169/.226 and lowered his season batting average from .211 to .180.
