Barajas, Davis each hit two HRs; Pelfrey solid into eighth

His left hand throbbing, the result of a freakish pitchout accident, Rod Barajas figured to have one swing left in him when he stepped to the plate Friday to face Giants reliever Sergio Romo in the ninth inning.

Francisco Rodriguez already had blown the save, serving up the tying homer to pinch hitter John Bowker, so it was left to Barajas, who just happens to be the Mets' most dangerous deep threat this season. Barajas' bruised index finger was hurting to the point that he didn't even take any swings in the on-deck circle. He couldn't risk it.

"I told myself that I probably had one good swing, and after that, my finger would go numb," Barajas said. "My whole body went numb after the ball went over the fence."

That's because Barajas drilled the 2-and-2 pitch into the leftfield seats for his second home run of the night. The first was No. 100 for his career, and the encore blast delivered the Mets' 6-4 victory over the Giants.

X-rays of his hand were negative. Barajas was asked numerous times if he needed to come out after Eli Whiteside reached for a pitchout and clubbed him on the glove hand in the seventh inning. Good thing for the Mets that he was stubborn enough to stay and help them extend their home winning streak to eight games. It is their longest since they reeled off a franchise-record 11 in a row from Aug. 5-24, 2006.

"I'm the type of player that once I start a game, I want to finish it," Barajas said.

Ike Davis made sure the Mets got that final chance. Davis slugged a pair of home runs off Giants starter Jonathan Sanchez, who had not allowed a homer in five previous starts this season - or any sort of hit at all by a lefthanded hitter (0-for-17).

"When I saw that on the scoreboard," Davis said, "I thought it was a mistake. That's not even possible."

Davis, 23, became the youngest Met to have a multihomer game since Lastings Milledge in 2007, but it took him only 16 games compared with 114 for Milledge. Still, Davis probably made as big an impact Friday with his glove, thanks to another acrobatic catch over the dugout fence on Pablo Sandoval's foul ball for the third out of the ninth inning.

Luis Castillo prevented the go-ahead run from scoring with a diving stop of Mark DeRosa's infield single, and with runners at first and third, Davis flipped over the fence for the catch. Davis made a similar catch on April 21.

"I don't know how I keep getting chances like that," Davis said. "I just try to get to the railing of the fence and go from there. I'm going to try and catch any ball that I can. It helps to have long arms, I guess."

With all of the late-inning heroics, Mike Pelfrey's stellar night went under the radar. Pelfrey passed an MRI exam earlier in the week after complaining of tightness in his shoulder, but the true test was this start - and he aced it.

Pelfrey cruised for 71/3 innings, the longest outing for a Mets starter this season, and needed only 85 pitches. He allowed eight hits and three runs but had to be rescued by Fernando Nieve with two on and one out in the eighth. Nieve got Juan Uribe to bounce into a forceout and Nate Schierholtz lined out to leftfield to end the threat.

Pelfrey said he still felt some tightness, but not nearly as much as last Saturday, which prompted the MRI visit. "So you guys don't come around asking all week," Pelfrey said. "I'm going to make my next start."
