Adams dealing with irritation in right biceps

MILWAUKEE -- Reliever Mike Adams can't seem to get healthy and stay healthy.

He spent time on the disabled list last month because of a strained back, but lately has been battling irritation in his right biceps. It made him unavailable in Friday's 5-4 loss to the Brewers.

"It's kind of been going on for a little bit," Adams said. "Not a long time. Maybe like the past week. I was just trying to battle through. I just came to them today and said if you can give me a day or two off to kind of let it calm down hopefully everything kind of gets a little better and you move forward."

Adams said he did not think the irritation is related to the thoracic outlet syndrome surgery he had in September.

"I don't think so," he said. "I've had this in the past. It's one of those things that gets irritated. Let it calm down for a couple days and usually am good to go after that."

He has allowed four hits, four runs, four walks, two home runs and struck out three in 5 2/3 innings in six appearances since he returned from the disabled list May 26. He has a 6.35 ERA in that stretch.

"It just seems like I get rid of one thing and something else pops up," Adams said.

Utley hopes to return in middle of June

MILWAUKEE -- Phillies second baseman Chase Utley said Friday he believes he can rejoin the team by the middle of the month.

"Yeah, it's realistic," he said.

Utley has been on the disabled list since May 21 with a strained right oblique. He said he already feels he can take a few swings with the bat, but will wait a little longer to avoid any chance of a setback. A strained oblique can be finicky.

"I am definitely feeling better," he said. "I'm hoping to take some swings in the next three or four days, and at that point, I'll probably know where I'm at."

Utley expects he will need some sort of rehab assignment, but it might be locally.

"We haven't talked about it, but I don't think Clearwater is in the plans," he said of the Class A Phillies affiliate that plays in that Florida town.

But a rehab game in Double-A Reading or Triple-A Lehigh Valley might be.

"Possibly, yeah," he said.

Phillies rotation staying afloat without Halladay

MILWAUKEE -- Roy Halladay threw his last pitch for the Phillies on May 5 and had shoulder surgery 11 days later, but it hasn't sunk the Phillies rotation.

Phillies starters entered Friday's game against the Brewers at Miller Park with a 3.36 ERA since Halladay's last start, which ranked fifth in baseball.

"They've been good," Phillies manager Charlie Manuel said. "A lot of times Tyler [Cloyd] and Jonathan [Pettibone], they get tested about every time they go out there right now because of their experience and they kind of are new at the Major League level."
