LOS ANGELES -- Â The Padres haven't played well at Dodger Stadium in 2009, and Tuesday night was no different. Chris Young matched a career worst by allowing four home runs, the Padres couldn't get a timely hit and their baserunning errors proved costly in a 6-4 loss to the Los Angeles Dodgers in front of 35,313.

The loss was the Padres' fifth in a row in L.A. this season, and 10th in 11 games here dating back to last September.

"I'm just not executing pitches," said Young, who fell to 4-5 after allowing five runs on six hits in five innings. "The balls hit out tonight weren't good pitches, and that's the bottom line."

Staked a 2-0 lead in the top of the first inning, Young saw his advantage cut in half when Andre Ethier lined a curveball over the right-field fence for a solo home run.

The Dodgers tied the game in the second on Matt Kemp's single and took a 3-2 lead on Ethier's solo homer in the third.

After Brian Giles tied the game in the fifth inning with an RBI groundout, Young allowed solo homers to Kemp and Orlando Hudson in the bottom of the inning as Los Angeles made it 5-3. Young, who has yielded 11 homers in his last six starts after giving up one in his first seven, also allowed four homers at the Chicago Cubs on May 13.

"I don't think there's one thing you can put your finger on," manager Bud Black said. "The hanging curveball (to Ethier) was not where C.Y. wanted it. And the next one was a fastball down and in that he meant to throw the ball away -- and that's Ethier's hot spot."

Tony Gwynn Jr. and David Eckstein have stayed hot at the top of the Padres' lineup. They each had three hits, combining to reach base seven times. Gwynn, Eckstein and Giles started the game with three straight singles. Later that inning, Kevin Kouzmanoff converted the opportunity with a two-out RBI single.

Taking a patient approach against Chad Billingsley (8-3), the Padres constantly had runners on base during his five-plus innings of work.

But Gwynn and Nick Hundley were thrown out trying to advance to third base on balls that got away from Dodgers catcher Russell Martin.

Hundley later left the game after he was hit by a pitch on the left wrist. He went for an X-ray after the game, though Black was hoping Hundley suffered nothing more than a bruise. Hundley said stadium doctors didn't believe he broke any bones, but he wasn't certain.

The Padres also struggled when their baserunning didn't betray them, going 2-for-12 with runners in scoring position. It didn't help that their best hitter, Adrian Gonzalez, drew two walks for the eighth straight game -- a franchise record.
