Pujols homers and Carpenter stymies Astros in 8-4 win

Albert Pujols hit a three-run homer and Chris Carpenter slowed the Houston bats in the St. Louis Cardinals' 8-4 victory over the Astros on Wednesday night.

Pujols connected on a 3-2 pitch from J.A. Happ and put it over the left-field wall in the second inning for his 27th home run of the season and 393rd of his career. He has homered in three of his last four games and moved into a tie with Cincinnati's Joey Votto for the NL lead in home runs.

Pujols, who had three hits, knocked Happ out of the game with his homer. Happ, in his second start for Houston since being acquired from Philadelphia on July 29, gave up six hits and seven earned runs in one inning.

Carpenter (12-3) allowed just two runs on four hits over 7 1-3 innings in improving to 9-2 at Busch Stadium this season. He struck out three, walked three, and also drove in the final run during a four-run outburst in the first inning.

Houston, had won seven in a row and had outscored the opposition 57-12 during its season-best winning streak. The Astros outscored St. Louis 27-8 in winning the first two games of the series.

St. Louis batted around in the opening inning against Happ (2-1). Five of the first six hitters reached base.

Matt Holliday, Allen Craig, Yadier Molina and Carpenter all had run-scoring hits. Felipe Lopez began the inning with a single and moved to third on a ground-rule double by Pujols before three successive hits each plated a run. Carpenter's two-out single up the middle brought in Craig.

Lopez and Colby Rasmus drew walks in the second to set the stage for Pujols' home run.

Happ went to a three-ball count on six of the 12 batters he faced.

Chris Johnson hit a two-run homer in the second inning for Houston, which had won six successive games in St. Louis. It was the fifth homer of the season for Johnson, who has 11 RBI in his last six games.
