PHILADELPHIA -- Jayson Werth tinkered with his stance and Derek Lowe fixed flaws in his mechanics.

For one game, their self-improvements worked and gave Los Angeles a rare win in Philadelphia.

Jeff Kent hit a three-run homer and Werth had a two-run shot during a nine-run fifth inning, and Lowe pitched seven strong innings to lead the Dodgers over the Phillies 10-2 on Wednesday night.

"That's what you need in order to jump start yourself offensively," Dodgers manager Jim Tracy said.

Kent drove in four runs, Werth also doubled, Cesar Izturis had three hits and the Dodgers finished with 14.

Werth, who came in hitting only .234, spent the last few days working with hitting coach Tim Wallach to find something that would bust him out of his slump.

"I just had enough of the way things were going," Werth said.

So had Los Angeles.

It was a rare laugher for the Dodgers, who have had little to be happy about lately and won in Philadelphia for the first time since Aug. 4, 2002, at now-demolished Veterans Stadium.

Lowe (6-10) has been a bust after leaving Boston for a $36 million, four-year contract to anchor the Dodgers' staff.

The right-hander has struggled with his mechanics and looked little like the pitcher who helped the Red Sox win the World Series. Against the Phillies, though, he regained his form, never facing more than five batters in an inning.

"The whole game was a game I needed personally, and the whole team, also," Lowe said.

Lowe, who was 0-5 with a 6.34 ERA in seven starts since beating Detroit 5-3 on June 6, allowed six hits, struck out five, gave up two unearned runs and walked none.

"For the first time in quite a while, we created some breathing room for him," Tracy said. "When he gets on his game like that, he's awfully tough to deal with."

Lowe was never in any trouble and stalled the recent surge of the Phillies, who lost for only the second time in eight games. He kept the ball on the ground and cruised until he gave up David Bell's two-run homer in the seventh.

"This was the way I pitched earlier in the year, mechanically and confidence-wise," Lowe said. "I got into really a bad string, but I realized it wasn't something that was going to fix itself. It was something I had to go try and figure it out."

The results were much better and he had plenty of offensive support.

The Dodgers' 397 runs coming into the game were the third-fewest in the NL and one reason why they had lost eight of nine. They found their offense against Cory Lidle (8-8) in the fifth, when the righty was rocked for the second straight start.

Werth got Los Angeles rolling when he hit an 0-2 breaking ball the opposite way to right for a two-run homer, his fifth of the year and the 25th allowed by Lidle.

Oscar Robles added an RBI double and Izturis' low, line drive RBI single to right one-hopped in front of Bobby Abreu and made it 4-0.

Kent later hit his 16th homer, a three-run shot to left that made it 7-0 and chased Lidle, who failed to get an out. After pitching just 3 1/3 innings in his last outing, Lidle gave up seven runs and eight hits in this one.

"Plain and simple, I had a lousy game plan and didn't execute on any of my pitches," Lidle said. "Even in the fourth inning when I didn't give up a run, I was missing pitches by a foot. If I'm not hitting my spots, it's going to be ugly."

Reliever Robinson Tejeda didn't fare much better. Mike Edwards singled for his second hit of the inning and Werth was hit in the left shoulder in his second at-bat of the fifth. Jason Repko drove in both runners with his first triple of the year for a 9-0 lead.

Lowe struck out swinging to end the inning -- he was the 13th batter -- and the Phillies listened to sarcastic applause as they headed toward the dugout.

"It's good to get some hits and get things going," Werth said. "That's one thing we haven't had in a while was a big inning, so it was nice."

Kent added an RBI single in the sixth.
