Weary Dodgers 'pen without Withrow in Arizona

PHOENIX -- Stephen Fife's short start Wednesday night left 5 2/3 innings of work for a Dodgers bullpen that is without rookie Chris Withrow, who left the club to be with his wife for the birth of their first child.

Although expanded rosters have swelled the Dodgers' bullpen to 11, manager Don Mattingly hoped Thursday starter Ricky Nolasco goes much deeper than the 1 1/3 innings of his last start.

"We needed as much from the team aspect as anything," Mattingly said. "We had to use some guys last night we didn't want to use."

Mattingly used six relievers in the 9-4 loss Wednesday night. Carlos Marmol entered in the third inning and pitched 1 2/3 scoreless innings. Brandon League followed with 1 1/3 scoreless innings. Ronald Belisario was credited with retiring only one batter, but he made 20 pitches while allowing a career-high five runs. Brian Wilson lowered his ERA to 0.96 with a scoreless inning. Paco Rodriguez and Peter Moylan also pitched.

Withrow has put himself in position for postseason roster consideration by striking out 38 with only nine walks in 29 2/3 innings.

Capuano hopes to be healthy for postseason

PHOENIX -- Chris Capuano, already on the bubble of what shapes up as a crowded postseason roster, hasn't given up on being a participant, even with his ill-timed groin strain.

On Wednesday, Capuano had a platelet-rich plasma injection, which he said will "marinate" for 48 hours before he tests it.

"We tried to be aggressive, but I felt it again off the mound, so we'll try this," Capuano said. "By the end of the season, I hope to be 100 percent and give them the option. I had good results with [a PRP injection] with my calf earlier."

Capuano said even if he isn't 100 percent to open the first round of playoffs, he plans to throw simulated games or work out during the Dodgers' Arizona instructional league to be ready if he's needed at any point of the postseason.

"My hope is to be throwing well and be available and see what happens," he said.

Capuano was about to be bumped as the fifth starter by the signing of Edinson Volquez when he left a Sept. 6 start in the second inning with a strain of the left groin and hasn't pitched in a game since.

Hanley back in lineup, but quad sidelines Adrian

PHOENIX -- Hanley Ramirez was in the Dodgers' lineup Thursday, but Adrian Gonzalez was not as injuries continued to dictate manager Don Mattingly's decisions.

Ramirez's back rebounded after a day off Wednesday, but the quad muscle that forced Gonzalez from Monday night's game is lingering.

"He said it was a cramp, but when he came out last night [by ejection], he said he feels something," Mattingly said. "I don't think it's major. He says he can pinch-hit and play defense. To me, it's more than a cramp and less than a full-blown injury, but it is enough to know he could use a day."

Jerry Hairston, 4-for-10 against Arizona starter Wade Miley, started at first base.

Mattingly said he will continue to play Ramirez when the medical department clears him, will sit him otherwise, acknowledging that it will be easy to rest Ramirez if and when the division is clinched.

"Even though it looks really good, we're not where we want to be," Mattingly said.

Mattingly said Andre Ethier's sprained ankle continues to improve and he probably will advance to taking batting practice on the field with the club in San Diego Friday.

Carl Crawford, who has been slowed by a stiff lower back, did not start because Miley is a left-hander and his replacement, Scott Van Slyke, has homered off Miley.
