Schierholtz to DL with broken toe; Phils call up Luna

MIAMI -- Manager Charlie Manuel planned to let Nate Schierholtz play almost every game for the Phillies the final two months of the season.

He wanted to get a real good look at his newest outfielder.

But Schierholtz, who the Phillies acquired on July 31 in a trade with the San Francisco Giants for Hunter Pence, could miss three to four weeks after he broke his right big toe during his at-bat in the 10th inning Sunday against the Cardinals at Citizens Bank Park. Phillies assistant general manager Scott Proefrock said they were still awaiting further word from team doctors, but the expectation is Schierholtz can return before the end of the season.

Proefrock said Schierholtz had done something similar to his toe a few days before. Sunday's at-bat, in which he fouled a pitch off his foot, broke it.

The Phillies recalled Hector Luna to replace Schierholtz on the 25-man roster.

Schierholtz had hit .219 (7-for-32) with one double, one home run and two RBIs in 11 games with his new team. He had started seven games in right field and two games in center field.

The injury comes at a bad time for Schierholtz, who was looking forward to playing regularly the rest of the season.

"We're aware of what he's capable of," Proefrock said. "We've seen him play multiple times over the course of the last three or four years. I don't think we're losing anything [in terms of evaluation]."

"There's a lot of things I like about him," Manuel said. "He's a strong right fielder. He's got a strong arm. He looks like he's going to handle right-handed pitching good."

Manuel said John Mayberry Jr. and Laynce Nix could play center field while Schierholtz is on the DL. Michael Martinez also has played there.

Worley to keep pitching with bone chip in elbow

MIAMI -- Phillies right-hander Vance Worley is pitching with a bone chip in his right elbow and is 2-3 with a 5.73 ERA in eight starts since the end of June.

So, naturally, a lot of fans have been asking if the Phillies could shut down Worley for the remainder of the season, despite the fact that he maintains the injury is not a factor in his recent struggles. The school of thought is Worley could have a surgical procedure to remove the bone chips and begin his road to recovery sooner rather than later.

But the Phillies said there has been no discussion about that.

"My understanding is the issue isn't going to take a whole offseason to recover from," Phillies assistant general manager Scott Proefrock said. "As long as he can still pitch and there's not a risk of him hurting himself ... and from everything I understand, there's no issue there. He's pitched some good games, he's pitched some bad games. You've got to remember last year was his first time around. The second time around, you've got to make adjustments. My impression is [Worley's struggles] are not related to the issue.

"I haven't been involved in any discussions whatsoever with shutting him down."

Polanco likely won't play every day upon return

MIAMI -- Phillies third baseman Placido Polanco has been on the 15-day disabled list since July 23 with inflammation in his lower back. He took batting practice Sunday and is getting closer to beginning a rehab assignment.

But whenever that happens and whenever Polanco returns, Phillies manager Charlie Manuel said it is unlikely Polanco will be an everyday player for the remainder of the season. Part of that has to do with Polanco's ability to stay healthy, but part has to do with the way Kevin Frandsen has played lately.

Frandsen was hitting .326 (15-for-46) with one double, one home run and two RBIs in his previous 13 games entering Monday.

"We definitely need him back," Manuel said. "He's a good defensive player."

Worth noting

Phillies shortstop Jimmy Rollins tied Larry Bowa for the most games played at the position in Phillies history (1,730).
