PHILADELPHIA -- Phillies outfielder Domonic Brown played in an extended Spring Training game Monday. He has been on the 15-day disabled list since the season started because of a fractured hamate bone in his right hand. Brown went 2-for-3 in five innings.

Chase Utley continued his running drills Monday afternoon at Citizens Bank Park. There is no timetable for his return, although he continues to progress.

Romero suffers strained calf in Phillies' loss

PHILADELPHIA -- It sounds like Phillies left-hander J.C. Romero is headed to the 15-day disabled list.

He will know more Tuesday. He strained his right calf in the ninth inning Monday in a 6-3 loss to the Brewers in 12 innings at Citizens Bank Park. Romero limped through the Phillies' clubhouse afterward.

"Probably, probably some time," said Romero, asked if he expected to be placed on the DL. "I don't know how long, but hopefully 15 days or so."

Romero recorded the first two outs of the ninth, when Brewers center fielder Carlos Gomez reached on an infield single. Romero hopped off the mound after throwing the pitch before dropping to the turf in pain.

"I was trying to push off the leg, and it kind of gave out on me," Romero said. "I knew something was wrong."

Romero, who will have a MRI on Tuesday, is 0-0 with a 3.86 ERA in seven appearances this season.

"I don't know what else could happen," Romero said. "This is just ridiculous. At least my arm is good."

Possible replacements for Romero, if the Phillies place him on the DL, include right-hander Michael Stutes and left-hander Mike Zagurski.

Oswalt expects to be ready for upcoming start

PHILADELPHIA -- Roy Oswalt left the Phillies' bullpen on Monday afternoon feeling pretty good about his back.

"I feel fine," he said.

He left Friday's game against the Marlins early because of a strained lower back, but threw 40 pitches in a bullpen session Monday without incident. He said he expects to make Thursday's scheduled start against the Padres at PETCO Park.

"I'm good," he said.

Phillies pitching coach Rich Dubee said he expects Oswalt to pitch, but will wait to see how Oswalt's back feels Tuesday to be certain.

Phillies' claim on Schlitter voided due to injury

PHILADELPHIA -- The Phillies claimed right-hander Brian Schlitter off waivers Feb. 15, but he never pitched because of an existing elbow injury. Before the Phillies claimed him, the Yankees claimed him from the Cubs on Jan. 5.

Major League Baseball ruled Monday that Schlitter must be returned to the Cubs because of the existing injury.

"Evidently, he was not fully healthy at the time we made the waiver claims," Phillies general manager Ruben Amaro Jr. said. "They were all voided."

Amaro would not say if the Phillies filed a grievance with MLB, but it is believed they did. Because Schlitter had to be placed on the 15-day disabled list to open the season, he was earning the big league minimum salary and earning service time.

"There's no foul play, just an error in judgment or whatever you want to call it," Amaro said. "It's unfortunate for us, because he's not 100 percent healthy."
