Roy Halladay looks to help the visiting Phillies ride the momentum of an impressive three-game sweep into Monday's opener against the Dodgers, who appear ready to officially part ways with Manny Ramirez.Philadelphia (73-57) limped into San Diego for the start of a seven-game road trip Friday after being swept in four games by Houston at Citizens Bank Park.The Phillies didn't waste any time dwelling on that performance. They finished a three-game sweep of the NL West-leading Padres with an emphatic 5-0 win Sunday, staying 1 1/2 games up in the wild-card race and leaving manager Charlie Manuel struggling to explain the past week."I can't," Manuel told the Phillies' official website. "I absolutely can't. No sense in me trying."The two-time reigning NL champs are also two games behind the Atlanta Braves in the NL East.The Dodgers (67-64), on the other hand, won the first four games of their road trip but finished with a pair of losses after falling 10-5 in Colorado on Sunday. They're 6 1/2 games behind the Phillies in the wild-card race.The game featured a pinch-hit appearance from Ramirez, who was ejected after arguing a first-pitch strike in what looks to have been the final act of his tempestuous tenure in Los Angeles. The Dodgers on Monday plan to let the 12-time All-Star go to the Chicago White Sox, who won his rights on a waiver claim Friday.No players are expected back in exchange for Ramirez, according to the Dodgers' official website. The club will, however, save the approximately $4.3 million he's owed the rest of 2010.Ramirez had been benched the previous four games in favor of Scott Podsednik, who may be one of a few Los Angeles hitters that's looking forward to facing Halladay (16-9, 2.22 ERA). Podsednik is 5 for 12 (.417) against the NL ERA leader, while Andre Ethier is 3 for 4 with a homer.Halladay will try to bounce back from his first loss since July 18. The former Cy Young Award winner gave up three runs over seven innings Wednesday against Houston, falling 3-2.The right-hander hasn't faced the Dodgers since 2007, but he'll hope to pick up where he left off. Halladay is 3-0 with a 1.50 ERA in three starts against Los Angeles.Hiroki Kuroda (9-11, 3.56), meanwhile, has had recent success versus Philadelphia. The Japanese righty went 1-0 with a 0.95 ERA in three starts against the Phillies from 2008-09, lasting at least six innings while allowing two hits or fewer each time.He's posted a 2.89 ERA in his past four starts overall, though Wednesday's outing at Milwaukee was his first win in that span. Kuroda gave up four runs over seven innings in a 5-4 victory."There's been many games where I've pitched really well, but I couldn't get the win," Kuroda told the Dodgers' official website. "It's a bit frustrating at times, but you've got to keep pitching tough and the results will come."Ryan Howard, Jimmy Rollins and Shane Victorino are a combined 0 for 19 against Kuroda.
