PHILADELPHIA -- Cole Hamels waved to an appreciative crowd that gave him a standing ovation after a mediocre outing.
Was it his last time wearing a Philadelphia Phillies uniform?
"I can't control it," Hamels said after a 6-5 loss to the San Francisco Giants in 10 innings Saturday.
The Phillies are hoping to re-sign Hamels before the 2008 World Series MVP becomes a free agent after this season. If a deal isn't reached before the July 31 non-waiver trade deadline, Hamels could be gone. Of course, that doesn't mean the Phillies couldn't re-sign him in the offseason. Hamels already has said he would be open to returning to Philadelphia, even if he's traded.
"I think that's up in the air," Hamels said when asked if he's optimistic he'll sign a deal soon.
This was hardly the pitching duel expected from two of the elite starters in the majors. Both allowed three homers and five runs. But they did their job with the bat.
"I figured he'd try to put one out," Cain said. "The most frustrating thing you can do is give up a homer to a pitcher."
It was the first time pitchers homered off each other in the same game since Atlanta's Kevin Millwood and Colorado's Denny Stark did it on May 18, 2002. The last time it happened in the same inning was May 14, 1990 when Montreal's Kevin Gross and Los Angeles' Fernando Valenzuela went deep in the third inning.
"It was nice," Hamels said. "I enjoyed it more after giving up my first ever homer to a pitcher."
The five-time defending NL East champions are 41-54 and moving closer to perhaps being a seller before the trade deadline.
Hamels allowed 10 hits in 7 2/3 innings on a career-high 128 pitches. The three-time All-Star lefty is seeking a contract perhaps bigger than the megadeal Cain signed before the season. Cain signed a $112.5 million, five-year extension in April. The deal guaranteed him at least $141 million over seven years, including this season's salary and a 2018 buyout.
Cain gave up five hits in eight innings. The five runs were tied for the most he's given up this year.
Cabrera walked to start the 10th against Jonathan Papelbon (2-4) and went to third on Posey's looping single to right. After Pablo Sandoval struck out, Blanco put down a perfect bunt down the first-base line and beat it out without a throw.
Blanco had missed a sign on a squeeze in the eighth. This time, the runner on third waited for contact before breaking toward the plate.
After Utley flied out to shallow left, Howard connected. He ripped a 1-2 pitch to the seats in right-center to give the Phillies a 5-4 lead. Howard, the 2006 NL MVP, has three homers in 11 games after missing the first 84 games recovering from surgery on his left Achilles tendon.
But the Giants tied it at 5 when Cabrera led off the eighth with his 10th homer. Hamels hadn't allowed three homers in a game since June 26, 2010, vs. Toronto. That was 67 starts ago.
Posey followed with a double and advanced to third on a grounder. He was caught trying to steal home when Blanco took a pitch instead of bunting.
Hamels gave up three homers in his previous five starts combined before giving up two in the third.
First, Cain hit a towering shot to left for his sixth career homer and first this season. With two outs, Posey hit an 0-2 pitch out to left to put the Giants up 3-1.
Hamels answered Cain in the bottom half by taking him deep to right for his first career homer, cutting the deficit to 3-2.
"Both pitchers made mistakes," Giants manager Bruce Bochy said. "They're as good as anybody in the league."
Phillies are an NL-worst 17-29 at home. ... Utley has four homers in 23 career at-bats against Cain. ... The Phillies had their 266th straight sellout, including postseason. ... Barry Zito (8-6, 3.75) opposes Joe Blanton (8-8, 4.79) when the Giants try to complete the three-game sweep Sunday.
