PHILADELPHIA -- Phillies shortstop Jimmy Rollins will play in a rehab game in Clearwater, Fla., again on Saturday -- his fourth, and most likely last, before being activated from the 15-day disabled list next week.

Phillies assistant general manager Scott Proefrock said Rollins made it through nine innings on Friday for Class A Clearwater healthy but will play there again tonight and be reevaluated.

"Everything went well last night, and depending on how things go tonight, he'll be evaluated," Proefrock said. "We'll see where we go from there. We're optimistic he will be available for us sometime next week."

Rollins went 1-for-3 with a walk and two runs scored on Friday. He has been out since May 22 with a strained right calf.

Injured reliever Ryan Madson also made progress Friday.

Madson felt good in his first bullpen session since breaking his right big toe on April 28 and having surgery on it in early May.

Madson threw 26 pitches and said everything felt fine. He will throw again on Sunday but does not know any plans for him beyond that.

Ruiz not DL-bound, but to miss games

PHILADELPHIA -- The Phillies are not putting catcher Carlos Ruiz on the disabled list following a hit to the head in the eighth inning of Friday's win over Minnesota. But Ruiz, who was dazed, but did not suffer a concussion, will be out of commission for at least a few days as he undergoes additional testing.

In the meantime, a tricky roster situation emerged for Philadelphia as it scrambled to find a backup catcher. Veteran Paul Hoover, who was brought up from Triple-A Lehigh Valley earlier this season, when Ruiz was on the disabled list, is currently out with a knee injury.

The Phillies added catcher Dane Sardinha to the 40-man roster and brought him up on Saturday morning. In a corresponding move, reliever Scott Mathieson was designated for assignment.

Phillies assistant general manager Scott Proefrock tried to sort out the process on Saturday.

"Basically, we designated him for assignment so we have 10 days to either trade him or assign him to the Minor Leagues," Proefrock said. "That could be an outright assignment, or an optional assignment. He has options left, and because we're not at 40 on the 40-man roster, that's still an option for us."

Ruiz was hit in the back of the head by a broken bat by Jason Kubel in the eighth inning on Friday. He left the field under his own power, but was taken to Thomas Jefferson Memorial Hospital for tests. Ruiz passed all the evaluations and did not suffer a concussion, Proefrock said.

Ruiz will be tested further Saturday and Sunday.

"We didn't want to DL him because we don't think it'll be that lengthy of a process, we're certainly hopeful it won't be," Proefrock said. "But we still need to have somebody who can catch for us."

Mathieson still has options left, but the Phillies made the decision to designate him for assignment and hope he clears waivers.

It is an abrupt turn to a fairytale 48 hours for the 26-year-old Mathieson, who appeared in his first game for Philadelphia on Friday after two Tommy John surgeries since 2007.

He arrived on Thursday in New York beaming after being called up with the injury to left-hander Antonio Bastardo. On Saturday, he was trying to sort out what exactly happened, and holding back some obvious disappointment.

"It's just kind of wait and see I guess," Mathieson said.

Mathieson allowed two runs in two-thirds of an inning Friday, but Proefrock said the move had nothing to do with his performance.

"It's a roller coaster, right?" Mathieson said. "Ups and downs. I was glad to be back up here. Yesterday wasn't what I was hoping for, but there will be another chance."
