PITTSBURGH — The Pittsburgh Pirates found a way to come back from an early deficit this time around.

Jose Bautista and pinch-hitter Doug Mientkiewicz had RBI singles in the eighth inning to cap a rally from a four-run deficit in the first inning for a 7-4 victory over the St. Louis Cardinals on Wednesday night.

It was the second win in a row after falling behind in the first inning for the Pirates, who found themselves in big deficits in five of the six games during a losing streak this modest win streak.

"During the six-game stretch we've had, (giving up) would have been very easy after falling behind like that," said Jason Bay, who hit a two-run homer. "You still would like to have a game where we're up 10-0 right off the get-go and cruise to a win, but we'll take it. A win's a win."

Freddy Sanchez had two hits and scored two runs, and Ian Snell rebounded after a rocky first inning to shut down St. Louis for the remainder of his six innings.

"You could tell things weren't really clicking for him early," Pittsburgh manager John Russell said. "His command was off and he didn't look like he was comfortable. But as the game went on, he seemed to get stronger. And that's a great sign for a quality pitcher, that he's able to fight through that and get stronger as the game goes on."

Damaso Marte (1-0) pitched two scoreless innings in relief to earn the win, and Matt Capps pitched a perfect ninth for his sixth save for Pittsburgh.

Skip Schumaker, Albert Pujols and Adam Kennedy each had a pair of hits for the Cardinals, who have lost four of five.

With the game tied at 4 in the eighth, Ryan Doumit singled to lead off the inning and scored on a two-out single by Bautista, who's batting .188 but has a hit in each of his past four starts. After Brian Bixler doubled to left, moving Bautista up to third, Mientkiewicz singled down the left-field line off Anthony Reyes (1-1) to make it 7-4.

The inning was made possible partly because of an errant throw by Reyes on a comebacker to the mound hit by Xavier Nady with Doumit at first and nobody out. Reyes' throw for the forceout at second was too high for shortstop Aaron Miles, but second baseman Adam Kennedy was backing up. He caught the ball and threw Nady out at first.

Though not ruled an error, a double play on that would've likely allowed Reyes to make it through the inning unscathed.
