The 21-year-old rookie pitched into the eighth inning and the San Francisco Giants got home runs from Pablo Sandoval and Aubrey Huff, sending the Cardinals to their season-worst fifth straight loss with a 6-3 victory on Friday night. All of the losses have come at home for St. Louis, which is 39-23 at Busch Stadium and has scored two runs three times during the slump.
"It's not just our offense, we need to play better," Pujols said. "There are lot of different things that we aren't doing the right way, and you can't win like that.
"There's no tomorrow, we need to win games."
Pujols hit his 398th career homer for the Cardinals, who led the NL Central by a game after a dramatic sweep of the Reds on Aug. 11, but have dropped five of six since then and began the night 3½ games behind Cincinnati. Pedro Feliz singled and scored twice and handled two chances at third base in his debut with St. Louis.
Pujols, who leads the NL with 32 homers, also lined a ball to the center field wall against Bumgarner in the third. Not that the rookie was overly impressed.
"You know what, I'm looking forward to facing him again," Bumgarner said. "I'm not going to be afraid, not going to try to go around him. I'm going to go after him."
The slump is getting to manager Tony La Russa, who complained about home plate umpire Gary Cederstrom's calls in the ninth inning while Brian Wilson was finishing for his 35th save in 38 chances.
"You can go ahead and fine me, I don't care," La Russa said. "There were several strikes, a guy as good as Brian Wilson, he doesn't need. Who knows how that inning would have been?"
Bumgarner (5-4) struck out five with one walk and worked out of trouble twice. Felipe Lopez popped up with the bases loaded to end the second when the Cardinals scored once on four hits, and Matt Holliday grounded into a double play with two men on to end the fifth.
Bumgarner was hurt only by Brendan Ryan's bases-loaded infield hit in the second and Pujols' homer leading off the eighth, also the last batter he faced. The left-hander had been 0-2 the last four starts but has won all of his games on the road, and has showed better velocity lately after backing off the intensity playing catch between starts.
"My arm's starting to feel better and better each time out," Bumgarner said. "It's helped me feel better each time out, the command's been there and I haven't been tired.
"I was throwing high effort level each day between starts and it just wears you down."
Pujols also singled and walked and tied Dale Murphy for 49th place on the career list after his ninth homer in 16 games.
Westbrook, the last Cardinals pitcher to win, allowed three runs on seven hits in six innings. The right-hander was in trouble in four innings, stranding two runners in the first and fifth, giving up two runs on four hits in the second, and surrendering Sandoval's 10th homer in the third.
The Giants had four hits in a stretch of five at-bats in the second, including Bumgarner's second career RBI on a single he bounced up the middle and Posey's RBI double.
Sandoval homered for the second straight game and fourth time in eight games, a stretch that followed a 47-game homerless drought. Huff had been 1 for 14 against the Cardinals before ending a 69 at-bat homer drought with his 21st in the seventh off Blake Hawksworth, and reached base four times adding a single and two walks.Notes
