CHICAGO -- Catcher A.J. Ellis is expected in Chicago for Friday's Dodgers game against the Cubs after being recalled from Triple-A Albuquerque, but he's expected to stay only until Hiroki Kuroda is activated off the disabled list, which could be as soon as next week.

That was the plan manager Joe Torre laid out after Thursday night's game, all of this triggered by Will Ohman.

Ohman was placed on the disabled list with what the club said was a sore left shoulder. The implication is that his 5.84 ERA is the result of an injury.

"It's been bothering me for a while," said Ohman. "Rushing to get ready, probably."

He said the shoulder has had "tightness and some pain." The rushing part, that's hard to argue. Ohman was a free agent who found no takers until the Dodgers came calling one week before Opening Day. He made the 25-man roster even after management said he wouldn't, mostly by default as other candidates faltered.

"I've had this problem before," he said. "The situation -- we're playing exceptionally well, and I haven't been doing my job. Everybody wants to be a tough guy. But this situation, you do what's best for the team."

Until Kuroda returns, the Dodgers will go with a seven-man bullpen, even though they were so hard-pressed with an eight-man bullpen Thursday night that backup closer Ramon Troncoso had to pitch two innings.

Torre said he expected closer Jonathan Broxton and setup man Ronald Belisario to be available Friday. Cory Wade did not warm up Thursday night. Guillermo Mota and Brent Leach warmed up but did not enter the game.

Leach will be the only left-hander in the bullpen until the Dodgers are satisfied that Kuroda is ready to return. He would likely bump a left-hander (Eric Stults or Eric Milton) out of the rotation and, possibly, into the bullpen as a second lefty to replace Ohman.

Pitching matchup
LAD: RHP Chad Billingsley (6-2, 2.82 ERA)
In his worst start of the year, Billingsley was staked to a four-run lead in the second inning and let it get away in a three-run sixth. Billingsley had trouble with his cut fastball and the Angels weren't helping because they wouldn't chase his breaking ball. He'll be facing the Cubs, who he beat in the playoffs last year.

CHC: LHP Ted Lilly (5-4, 3.77 ERA)
Lilly is coming off an up-and-down start against the Padres in which he allowed five runs on eight hits, walking two and striking out four over 6 1/3 innings. He has pitched six or more innings in 142 career starts, going 83-32. Lilly has thrown six or more innings in seven starts this season, but he has lost his past two starts and received just two runs in support of his pitching.
