MIAMI -- Phillies manager Charlie Manuel said right-hander Joe Blanton felt some soreness in his right elbow Monday, when he pitched five innings in his return from the disabled list.

Manuel could not say if Blanton, who was on the DL with a medial impingement in the elbow, is in danger of missing Saturday's start in Atlanta. The Phillies should have a better idea Wednesday, when Blanton throws in the bullpen.

"As far as I know, he's fine," Manuel said. "My understanding is he doesn't feel 100 percent yet."

"I don't have any reason not to be [optimistic he will start Saturday]," pitching coach Rich Dubee said. "I haven't seen him throw yet."

Oswalt, Ruiz expected to join Utley in Clearwater

MIAMI -- Class A Clearwater could have a big league Phillies feel Thursday at Bright House Field.

Not only could Phillies second baseman Chase Utley be in the lineup, but right-hander Roy Oswalt is expected to start and catcher Carlos Ruiz is expected to be behind home plate.

Oswalt and Ruiz are both on the disabled list with lower back inflammation. Oswalt threw a bullpen session before Tuesday's game against the Marlins at Sun Life Stadium, and he said it went well. Ruiz is scheduled to play in extended spring training games Tuesday and Wednesday in Clearwater before playing an official rehab game with the Threshers on Thursday.

"The back feels great," Oswalt said. "A little rusty. I can't spot my fastball and don't have any breaking pitches."

He smiled.

"Other than that, I'm in pretty good shape," he said.

Oswalt seems fairly confident he will lose the rust in Thursday's rehab start.

"Let's hope so," he said.

If Thursday goes well, Oswalt is expected to be activated for Tuesday's game against the Cardinals at Busch Stadium. If Ruiz feels good, he could be activated before this weekend's series against the Braves at Turner Field.

Phillies prospect Brown tearing up Minors

MIAMI -- The Phillies like to say a Minor League prospect will tell them when he is ready to play in the big leagues.

Domonic Brown is saying something in the Minor Leagues. In 52 plate appearances with Class A Clearwater and Triple-A Lehigh Valley, he is hitting a combined .378 with two doubles, four home runs, 10 RBIs, five walks, nine strikeouts, one stolen base and 11 runs scored.

That is noteworthy for three reasons. First, Brown is the Phillies' top prospect. Second, Phillies left fielders entered Tuesday's game ranked 13th in the National League with a .677 on-base-plus-slugging percentage. Third, Phillies right fielders ranked 10th in the league with a .731 OPS.

Phillies manager Charlie Manuel could not say how many at-bats Brown needs in the Minors or when he might be ready to help the Phillies. But he certainly sounds like he would welcome some offensive production, if Brown could provide it.

"I'm an individual in some ways," Manuel said. "If we bring up Domonic Brown, we're going to play him."

Worth noting

Phillies right-hander Jose Contreras threw a light bullpen session Tuesday. Contreras is on the disabled list with a strained right flexor pronator tendon. Pitching coach Rich Dubee said it went well. ... The Phillies named first baseman Joe Savery and right-hander J.C. Ramirez their Minor League Player and Pitcher of the Month, respectively. Savery, who is converting from a pitcher to a hitter, hit .450 with six doubles, two triples and one home run in April with Class A Clearwater. Ramirez, who the Phillies acquired from Seattle in the Cliff Lee trade, went 4-0 with a 1.03 ERA for Double-A Reading.
