HOUSTON (AP) -- Carlos Lee's grand slam was one of three homers that lead the Houston Astros to an 11-6 win over the St. Louis Cardinals on Tuesday night.
The Astros led 5-1 before Lee's shot to the Crawford Boxes in left field in the seventh inning. It was his second grand slam of the season and his second straight day with a home run.
Geoff Blum followed Lee's home run with his own to right field to push Houston's lead to 10-1.
Hunter Pence added a two-run homer and Miguel Tejada drove in three runs to help the Astros beat the NL-Central leading Cardinals for the second straight night.
Astros starter Wandy Rodriguez (10-6) allowed four hits and one run in seven innings for his 10th win of the season, his most since going 10-10 in 2005.
