He made sure it wasn't necessary.
Loney homered in the 13th inning, giving the Dodgers a 3-2 victory on Saturday. The easygoing first baseman's seventh homer of the season was even more timely because manager Joe Torre had no true relievers left in his bullpen.
"I was getting ready to pitch, just in case," Loney said. "I just got my new pitchers gloves. See them there in my locker?"
"I just went up there looking for something I could drive, and luckily I got it," Loney said. "I've had some walk-off RBIs before -- a single and a walk. But a walk-off home run is definitely a different experience."
Perez was activated from the disabled list Tuesday.
"It was one mistake. I wanted to throw one down on the corner, but I missed up and he hit it well," said Perez, who escaped a bases-loaded jam in the 12th by retiring pinch-hitter Jamey Carroll on a fielder's choice grounder. "Everybody can make mistakes. Today I was the guy who lost the game."
Much-maligned reliever George Sherrill (1-1), the ninth Dodgers pitcher, worked a perfect inning.
"It was lonely down there," said Sherrill, who came in with a whopping 7.48 ERA. "I could have gone as many innings as they needed until they took it from me. I was prepared to go back out there. I was prepared to and ready to -- I actually wanted to. But luckily, James got a hold of one."
Kenley Jansen, a hard-throwing 22-year-old who began his pro career as a catcher and was converted to a pitcher during his 2009 season with Class-A Inland Empire, worked a perfect seventh for the Dodgers in his major league debut. The 6-foot-5, 257-pound right-hander struck out his first batter, Angel Pagan, on three pitches and then fanned All-Star David Wright.
"I feel great. It was just awesome being out there," said Jansen, who was born in Curacao, Netherlands Antilles. "When they told me last year in Triple-A that they wanted me to pitch, I didn't believe I could do it. It's just awesome that in less than a year, I'm pitching in the big leagues."
Dodgers rookie Carlos Monasterios scattered six hits and struck out three in his seventh start this season and first since June 18. The right-hander pitched out of a bases-loaded jam in the fourth, fanning Rod Barajas and pitcher Mike Pelfrey.
Barajas trimmed the Dodgers' lead to 2-1 in the sixth with an RBI single off James McDonald, just his fourth RBI in a span of 101 at-bats. But he strained his right oblique muscle running to second when the next batter, pinch-hitter Jeff Francoeur, hit a squibber toward the mound. McDonald bobbled it before flipping the ball to catcher Brad Ausmus -- thinking that Jason Bay was coming down the line from third.
Henry Blanco replaced Barajas on the basepaths, and Jose Reyes tied the score with what would turn out to be the Mets' final hit of the game an RBI single off newly acquired Jack Taschner. The bases remained loaded for Luis Castillo, who grounded into an inning-ending double play. The Mets are batting a major league-worst .209 in bases-loaded situations.
Pelfrey allowed two runs and six hits through five innings in his Dodger Stadium debut. He threw 45 pitches over the first three innings -- six fewer than he made in the first inning of his previous start, when he lasted only 1 1/3 innings at Arizona.
For the eighth time in his last nine outings, Pelfrey gave up a run in the first. Rafael Furcal led off with a single, advanced all the way to third on Pelfrey's errant pickoff throw and scored on Xavier Paul's sacrifice fly. The Mets' 6-foot-7 right-hander had allowed only one first-inning run through his first 11 starts this season.
Ausmus, who was put on the disabled list during the first week of the season because of a back injury and didn't come off until Tuesday, made his second start behind the plate in place of Russell Martin and got an RBI single in the fourth to increase the margin to 2-0.
The Mets have not won consecutive road games against NL teams all season.
Dodgers All-Star right fielder Andre Ethier, who entered the game in a 4-for-29 rut with two homers and three RBIs since the break, did not start for only the second time since coming off the DL on May 31. He pinch hit in the 10th and struck out, then fouled out to Blanco in the 12th with runners at second and third.
"He's just been struggling. It looks like he's just fighting it," Torre said. "Last night I talked to him a little bit, and you could see there was a lot of frustration going on."
The Mets are 175-178 since Jerry Manuel replaced Willie Randolph as manager. Randolph was 199-154 through his first 353 games. ... Dodgers closer Jonathan Broxton escaped a jam in the ninth by striking out Wright with runners at second and third. Wright is 1-for-7 with five strikeouts against him.
