He lined a homer to the opposite field, right, to give the Cardinals the lead in the eighth. Then, after the Astros tied the score, Pujols launched a long two-run homer to left in a three-run 10th.
"I knew I was going to have a good day," said Pujols, who drew his usual torrent of boos from the Houston crowd. "I love it when they boo me. They're doing it for a reason."
The homers were Nos. 18 and 19 for Pujols in the regular season at Minute Maid, not counting his legendary playoff homer there off right-hander Brad Lidge in 2005.
Pujols' second homer of the game came after a one-out homer in the 10th by left fielder So Taguchi, who had just one at-bat after coming into the game on a double switch.
CARDINALS 8, ASTROS 6 (10 innings): The Cardinals hit a season-high five homers, four of them solo shots, as they won a three-game series from the Astros for the third time this season. All the series have been 2-1 victories for the Cardinals. The Cardinals failed to draw a walk and left just two men on base.
