Cain shoots for elusive 13th victory

San Francisco (71-59) vs. Colorado (72-58), 1:05 p.m. PT

SAN FRANCISCO -- Matt Cain admits the ongoing journey toward win No. 13 has taken what "seems like forever."

In reality, it's only been 36 days -- a span that includes six winless starts.

Anyone floating around in the baseball realm, though, knows that may as well be deemed an eternity.

"Sometimes that's the way it goes," Cain said before Saturday's victory against the visiting Rockies. "I don't know what it is about that 13th win, but I hope it comes soon."

And by soon, the right-hander means Sunday.

Coincidentally, the Giants will be wrapping up a significant three-game set against division foe Colorado -- the last team generous enough to hand over a win to Cain.

That victory came July 24 at Coors Field. Since then, Cain has fallen victim to poor run support. Nothing new for the 24-year-old, who has thrown eight quality starts this season -- including two scoreless efforts -- which have resulted in no-decisions.

"You can only control what you do on the mound," he said. "If I keep going out there and battling, the wins will come."

Until Saturday, Cain wasn't the only one sitting in the waiting room for No. 13. Buddy Tim Lincecum endured four consecutive winless starts before toppling Colorado in Friday's weekend opener for the victory.

"Now that he's got it," Cain said with a smirk, "I better get it. We've both been waiting a long time."

Although Cain did not pitch during last week's four-game series in Colorado, he admitted his time spent as an onlooker from the bench may only aid in Sunday's effort.

"It's tough to sit there and not be able to help the team out when you're not pitching," he said. "At the same time, you're able to do some scouting and catch on to some tendencies of the other team. I can definitely use that to my advantage."

Cain is 7-5 with a 3.11 ERA in 15 career starts against the Rockies, who are battling the Giants for the National League Wild Card.

Pitching matchup
SF: RHP Matt Cain (12-4, 2.39 ERA)
Cain is winless in his last six starts, but don't let that fool you. He has a 2.72 ERA in this span, walking nine and allowing 36 hits in 46 1/3 innings. He's also 6-2 with a 2.28 ERA at home this season. Cain has pitched at least seven innings in all eight of his starts since the All-Star Game, hiking his season total to 177 1/3 innings and putting him just a few outings away from reaching the 200-inning level he covets so much. Cain's 2-1 with a 2.84 ERA in three starts against Colorado this year.

COL: RHP Jason Hammel (8-7, 4.43 ERA)
Hammel has been on a roll his last two times out, pitching seven innings of three-hit, one-run ball in Washington and another seven innings of two-run ball in the Rockies' extra-inning win against the Dodgers on Tuesday. It was his longest outing of the year at Coors Field, where he has made significant improvements his last three starts. He has consistently performed better on the road this year, posting a 6-4 record and a 2.88 ERA away from Colorado. He has one previous start in San Francisco this season, pitching six innings of shutout ball in a game the Rockies went on to lose 1-0 in May. He has been aggressive in his approach to hitters in his recent starts, leaning on his four-seamer and mixing in his curve and cutter to good effect.

Catcher Bengie Molina, who has not started the last five games due to a tight right quad, "is doing better," manager Bruce Bochy said. "He could go, and he's been available to pinch-hit. He'll get back in there in the next couple days." ... Aaron Rowand was out of Saturday's lineup nursing a sore shoulder that was hit by a pitch during Friday's game. Bochy deemed the outfielder day-to-day. ... Freddy Sanchez, who was placed on the 15-day disabled list Tuesday with a strained left shoulder, should be available to return to the 25-man roster when eligible Wednesday, Bochy said. The skipper mentioned Sanchez will likely make one or two rehab starts before that time. ... Bochy announced before Saturday's game that Randy Johnson (shoulder) will be with the team Sunday. The left-handed veteran, who has not pitched since July 5, has been playing catch on flat ground -- at distances up to 80 feet -- in Arizona. The first 20,000 fans through the gates Sunday will receive a Randy Johnson bobblehead. ... With rosters expanding in four days, Bochy told reporters Saturday he's ideally looking for "two or three more arms and some speed," along with "more depth in the infield."
