MILWAUKEE -- Chase Utley is unlikely to rejoin the Phillies next week in Houston, but they said they got good news on his concussion Saturday.

Concussion specialist Rob Franks examined Utley at Rothman Institute in Philadelphia, where he administered an ImPACT test. The results showed Utley near his baseline test, which he took in Spring Training. That has allowed Utley to begin exercising to see how he responds to exertion. Utley will have a follow up ImPACT test Monday, when Franks will reevaluate him.

"Based on that examination we'll have a better idea of when he will return to play," Phillies assistant general manager Scott Proefrock said.

But while Proefrock said it is unlikely Utley rejoins the Phillies for next week's three-game series in Houston, it sounds like Utley could be back sometime later next week.

"It's positive," Proefrock said. "Very positive. Good news. We're going to be very cautious, obviously. But it seems like he's making progress. We'll make sure he's 100 percent before we get him back on the field."

Utley has no symptoms from the concussion. Proefrock said Utley "felt a little foggy" when he was hit in the helmet with a pitch Wednesday at Citizens Bank Park, but never experienced any headaches.

Madson locks down save No. 30

MILWAUKEE -- Before the season started, the Phillies were not sure if Ryan Madson had a closer's mentality.

Thirty saves later it appears he does.

He picked up his 30th save in Saturday's 3-2, 10-inning victory over the Milwaukee Brewers at Miller Park. Madson is 4-2 with a 2.68 ERA.

"That proves he can do it," Phillies manager Charlie Manuel said. "He's done a tremendous job for us. He gets in the fire sometimes, and he can get out of it. He has talent. He has talent and three good pitches. His changeup plays up big."

Manuel says Bastardo will 'be fine'

MILWAUKEE -- Antonio Bastardo isn't overworked or tired.

That is the professional opinion of the Phillies, although Bastardo hasn't been sharp at all in his previous three appearances. He has faced eight batters, allowing two hits, four walks and four runs in one-plus inning.

"He needs his edge and his confidence," Phillies pitching coach Rich Dubee said. "He needs to start attacking the strike zone."

"He needs to go out and have a good inning," Phillies manager Charlie Manuel said. "I think he'll be fine. Go out, have a good inning and feel good about himself."

Bastardo allowed a single and a walk in Friday's 5-3 victory over the Milwaukee Brewers at Miller Park. Afterward he said, "I was tired, but now my mechanics feel a little bit weird. I've got to get my focus back to get first-pitch strikes. I've got to get back to work and attack the strike zone. I have to figure it out. I don't feel too tired because I just had four days' rest. In my mind, I'm not tired at all. But I don't know if my body feels good."

Rollins returns as pinch-hitter

MILWAUKEE -- Jimmy Rollins offered a multiple choice question on his Twitter account (@JimmyRollins11) Saturday:

What day shall I make my return?

1) Sunday.

2) Monday.

3) Tuesday.

The answer, it turned out, was, "4. None of the above."

Rollins had been sidelined because of a strained right groin, but made an appearance in the 10th inning as a pinch-hitter in the Phils' 3-2, 10-inning victory over the Brewers, grounding out to shortstop. Philadelphia shortstop Wilson Valdez injured his left hamstring stealing second base in the eighth inning, and ultimately had to be replaced.

Phillies manager Charlie Manuel said Valdez cannot play Sunday, but he will have Michael Martinez at shortstop and Pete Orr at second base. Manuel said Rollins will be available Sunday, but he will not return to the starting lineup until Monday in Houston.
