Houston, TX (My Sportsbook) - Carlos Lee crushed a decisive three-run homer, and Shawn Chacon posted his first win of the season after hurling seven strong innings in the Houston Astros' 5-3 clipping of the Chicago Cubs to earn a series win at Minute Maid Park.

Chacon (1-0) allowed three runs on five hits and a walk while fanning five for the Astros, putting to rest his major league-record nine consecutive no- decisions by a starter to open a season. Jose Valverde tossed a scoreless ninth -- striking out two -- to earn his 14th save.

Miguel Tejada and Geoff Blum each drove in a run for Houston, which has triumphed in three of its last four and nine of 13. Michael Bourn finished 3-for-5 with a triple, run scored and a stolen base.

Derrek Lee launched a two-run homer for the Cubs, who have dropped back-to- back contests after winning five of six. Geovany Soto added an RBI, and Micah Hoffpauir recorded two doubles and scored once.

Chicago won the first series of the campaign between the squads, 2-1, at Wrigley Field during the opening week of the season, only now to have the trend reversed.

Sean Gallagher (1-1) absorbed the loss, surrendering eight hits and five runs while striking out four over 4 2/3 innings. The Chicago bullpen kept the game close, working 3 1/3 scoreless stanzas.
