Toeing the rubber for the Giants will be Madison Bumgarner, who is in pursuit of his sixth consecutive win. Since dropping his 2012 debut on April 7 to the D-backs, Bumgarner is 5-0 with a 1.54 ERA, 19 strikeouts and seven walks. The left-hander has gone at least seven innings in four of his last five outings, surrendering just one earned run in each those four starts.
Bumgarner is 3-1 with a 3.11 ERA in seven games (six starts) lifetime against the D-Backs. Arizona tagged him for four earned runs on seven hits over four innings on April 7.
Countering Bumgarner will be Patrick Corbin -- the D-backs' No. 8 prospect, according to MLB.com. Friday marks Corbin's third career start since his debut on April 30 against the Marlins.
Corbin is looking to rebound from a brief outing on May 5 against the Mets, one that lasted just 3 1/3 innings in which he gave up four earned runs on five hits. However, the series opener will also be his home debut, and the D-backs will be looking to end a five-game losing skid.
"I'm definitely excited," Corbin said. "It's good to be here. I've never thrown here before. Definitely looking forward to it. I got to see one Spring Training game here, and I've been to a couple other games, but that's it.
"It's been a little overwhelming, but I'm starting to settle down and get used to some things," Corbin continued. "It's exciting and I'm glad to be here, but it's still baseball and you have to go out there and compete."
Giants: Pitching leading the way
Despite Tim Lincecum's shaky outing on Wednesday, Giants pitching has supported the club throughout much of the early schedule. San Francisco starters have allowed three earned runs or fewer in 19 of their last 21 games with a 2.60 ERA (39 earned runs in 135 innings). Giants starters have also allowed just one home run in the past 12 games and 18 roundtrippers on the season.
D-backs: Kubel comfortable in new digs
Outfielder Jason Kubel has settled right into his new ballpark. Kubel, who signed a two-year deal with Arizona last winter, is hitting .288 (15-for-52) at Chase Field, including all three of his home runs this season. However, Kubel had his 11-game home hitting streak snapped on Wednesday. He hit .350 (14-for-40) during the streak.
Cody Ransom has proved his value since being recalled from Triple-A Reno on April 22. In 11 games, Ransom is hitting .317 with four home runs and a career-high 12 RBIs. Ransom has tallied four multi-hit games and five games with multiple RBIs.
Wade Miley collected a hit during his start for the fifth consecutive time. It is the longest hit streak by a D-backs pitcher since Barry Enright's five-game streak from July 20-Aug. 10, 2010.
The Giants are 14-0 when either leading or tied after eight innings this season.
In their last seven home games, the D-backs are hitting .346 (18-for-52) with runners in scoring position.
