Blake DeWitt hit a two-run homer in the second inning to put the Los Angeles Dodgers ahead to stay, and they went on to hand Ervin Santana his first loss of the season with a 6-3 victory over the Angels on Saturday.

Chan Ho Park made his first start for the Dodgers in almost seven years, limiting the Angels to two runs _ one earned _ over four innings. The 34-year-old right-hander gave up three hits, walked two, hit Vladimir Guerrero with a pitch and struck out three. He left with the Dodgers up 4-2.

Because Park pitched just four innings, Hong-Chih Kuo (3-1) earned the win by shutting out the Angels for four innings. He held the Angels to two hits, struck out four and walked none.

Santana (6-1), coming off his worst outing of the season, gave up four runs on five hits in six innings. He walked three, hit a batter and struck out five.

The Angels' right-hander was tagged for nine hits and five runs in 5 2-3 innings at Tampa Bay last Sunday, but didn't get a decision in the 8-5 loss.

Park's most recent start in the majors was April 30 of last year with the New York Mets. His last with the Dodgers was on Oct. 5, 2001, when he gave up Barry Bonds' 71st and 72nd homers of the season.

Park, who began his major league career with the Dodgers in 1994, averaged 15 victories for them between 1997 and 2001 before signing with the Texas Rangers as a free agent for the 2002 season. He rejoined the Dodgers after stints with the Padres and Mets.

He has been effective out of the bullpen this season, going 1-0 with a 2.16 ERA in 12 appearances.

The Dodgers padded their lead to 6-2 with one run each in the seventh and eighth innings. Juan Pierre was able to score from third in the seventh when Russell Martin tried to steal second and was tagged out in a rundown.

The Angels scored their final run in the ninth when pinch-hitter Juan Rivera led off with a double against Takashi Saito and came home on Erick Aybar's infield single.

After falling behind 4-0, the Angels scratched out two runs in the fourth, thanks in part to a throwing error by first baseman James Loney.

With one out in the bottom of the third, Park plunked Guerrero after Santana hit Pierre in the top of the inning. Garret Anderson followed Guerrero with a single to right, putting runners at the corners. Maicer Izturis then grounded to first, but Loney's throw to second for an attempted force play sailed into the outfield.

So on what could have been an inning-ending double play, the Angels instead got a run when Guerrero came home. Robb Quinlan followed with an infield single to score Anderson from third.

The Dodgers took advantage of Santana's control problems to score twice in the second inning and add two more runs in the third.

The Angels' right-hander walked Andruw Jones with two outs in the second and DeWitt then hit a two-run home run, his fourth homer of the season. In the third, Santana walked No. 9 hitter Chin-lung Hu leading off, then hit Pierre with a pitch. Andre Ethier and Martin each then singled in a run.

Notes:@ Dodgers RHP Brad Penny was scratched from Sunday's start in Anaheim because of arm stiffness. RHP Derek Lowe will move up a spot in the rotation to replace him. ... Dodgers manager Joe Torre thinks Ethier is the most emotional player in the dugout during games. "He's my Paul O'Neill," Torre said, alluding to the former Yankees outfielder. "When I first took over the Yankees, I heard how selfish Paul O'Neill was. Then I realized that people's idea of selfish was that he wants to get a hit every time up. That's how I see Andre Ethier. He takes his (frustration) out on equipment, as did O'Neill. One time I told O'Neill, `Do what you want _ but if you get hurt to the point where you can't play, I'm gonna kill you."'
