The defending NL West champion Padres have lost four straight and seven of 10. Their offense finally bottomed out, with their last 19 batters being retired. The first five batters in San Diego's order went 0-for-16, with four walks.
"I think you've got a club that is pressing as bad as it can right now," Padres manager Bruce Bochy said. "It's frustrating for all of us, believe me."
San Diego entered the game last in the majors in home batting average, .210, and lost for the 10th time in 13 games at Petco Park this season. They've been shut out twice in three games and have been held to two or fewer runs in seven of their last eight games, all at home.
"This has gone on quite a while now," Bochy said. "It's probably the longest one I've seen a club go through. Hopefully, when we come out of it, we'll come out if it for a long time, too."
Seo (1-2) came in with a 7.64 ERA, having lasted only 3 2/3 innings in his previous start, a 5-4 loss to Arizona last Saturday.
All he needed to get better was a crack at the Padres, who wasted a nice effort by Chris Young.
Seo went six innings, striking out four and walking four. He allowed a single by Adrian Gonzalez and a double by Khalil Greene, both in the second inning. After issuing consecutive two-out walks to Brian Giles and Mike Piazza in the third, Seo retired the last 10 batters he faced.
"The difference was just the level of confidence," Seo said through an interpreter.
He said he spoke three days earlier with manager Grady Little, who encouraged him to work inning by inning and not look ahead.
"After the second inning, that boosted up my confidence," he said.
"Jae pitched a heck of a game," Little said. "The location of his pitches is a simple thing for that guy. He's not a guy who's going to blow anyone away with his velocity, so it makes his location that much more important," Little said.
Drew has reached base safely in all 20 games in which he's played this season, and 32 straight dating to last season. His two-run single was the third straight hit off Alan Embree opening the eighth.
"Jae threw the ball great and the game was moving along quick," Drew said. "When you get that kind of thing, you hope you generate enough offense, and we had a run to give him a lead when he left, and it was nice to get those two to kind of solidify things and give our bullpen a chance to work."
Young (2-2) struck out seven while allowing one run and five hits in 6 2/3 innings. He started three days after he began taking medication for a circulation problem in his right thumb that had caused it to feel numb in earlier starts. He walked two.
Young said his thumb bothered him as the game went on.
"I think that's only natural," he said. "All in all, I felt it was a non-factor for the most part."
- The Padres had their projected opening day lineup on the field for the first time this season. CF Mike Cameron started the season on the disabled list and was activated on Sunday. But with other starters getting days off this week, it took until Friday night for the projected lineup to be on the field.
- Navarro, the Dodgers' catcher, got his first career stolen base in the ninth.
