Game of the Day

Los Angeles at San Diego. If the Padres are to remain in the wild-card hunt, they need to sweep the Dodgers in this two-game series. They won last night's opener, 9-4. If they had lost both games they would have been all but out of the hunt, despite having six games against the dreadful Arizona Diamondbacks remaining. Brad Penny (9-9) gets the start for Los Angeles against Jake Peavy (12-6).

Player to Watch

Roy Oswalt, Houston. Along with Roger Clemens, Oswalt -- who goes for his 19th win tonight in San Francisco (ESPN2) -- has been a mainstay for the Astros during their hot streak. Through last night, the Astros were 22-7 in the past 31 days. Oswalt hasn't faced Barry Bonds, the possible NL most valuable player, since the season-opening series at Minute Maid Park in Houston, when Bonds had two doubles and a homer.

"I don't walk anybody on purpose unless I'm ordered to," Oswalt said. "I'm going to go after him if they let me. You have to make your pitch to him. If you miss, even by a little, it will wind up in the water" in McCovey Cove.
