D-backs call on Corbin in finale with Giants

Corbin tries to bounce back from rough start as D-backs go for series win over Giants.

After dominating opposing hitters for most of the season, All-Star left-hander Patrick Corbin has been mired in a bit of rough stretch for the Diamondbacks.

Corbin looks to bounce back from his worst outing of the season when he tries to help the D-backs win their third straight home series Sunday against the Giants.

After yielding two runs during his second complete game of the season against the Reds on Aug. 20, Corbin (13-4, 2.79 ERA) allowed a career-high nine in 5 1/3 innings of a 9-5 loss in Philadelphia last Sunday.

"It just wasn't my day," he said. "I left a lot of pitches up. I didn't have my best stuff. I feel bad about not going deeper into the game."

Since going 12-1 with a 2.31 ERA in his first 20 starts and earning a spot on the NL All-Star roster, the left-hander is 1-3 with a 4.35 ERA in the last six.

Corbin, however, has given up just three runs in 14 2/3 innings while not factoring in the decision in two victories over the Giants (60-75) this season.

The Diamondbacks (69-65) snapped a three-game home slide to the Giants by beating them for the second time in eight meetings at Chase Field with a 4-3 win Saturday. Eric Chavez delivered a game-winning single in the ninth as the D-backs bounced back after stranding eight runners in Friday's 1-0 loss.

They've posted 12 walk-off victories and 29 comeback wins this season.

"We've been good at it, it's just not a fun way to play baseball," Chavez said. "We've played so many extra-inning games, you just don't want to play like that. But we are good late. I don't know what that means, but that was a good one."

That single is Chavez's only hit in 12 at-bats over five games since a stint on the disabled list due to hip and knee problems.

"He came to me during (batting practice) and said, 'My swing stinks right now, but I might come through in a big spot,'" manager Kirk Gibson said. "He hung tough a got a good pitch."

Teammate Martin Prado, meanwhile, added three hits and in August hit .374 with 30 RBIs in 26 games.

San Francisco's Hunter Pence had three hits Saturday and is batting .355 in his last eight contests. He's 8 for 17 his last four games at Arizona.

Former Diamondbacks starter Yusmeiro Petit (1-0, 3.18) takes the mound for the Giants looking to build on his first start of the season, when he gave up two runs and struck out six in six innings of a 5-3 victory in Colorado on Tuesday.

"He's been around, knows what he's doing out there," manager Bruce Bochy told the Giants' official website. "He showed it (Tuesday)."

Recalled from Triple-A Fresno to replace the injured Matt Cain, Petit has made three appearances and two starts for the Giants since the start of last season. The right-hander went 9-19 with a 5.05 ERA in 56 games -- 35 starts -- for the D-backs from 2007-09.
