Oswalt remains unsigned; Philly return possible

CLEARWATER, Fla. -- Roy Oswalt remains a free agent, and his agent said Thursday that Oswalt might wait to sign until later in the season.

Don't be surprised if the Phillies make a run at him, if they need him.

While there are multiple reports Oswalt's top two choices are the Cardinals and Rangers, a source told MLB.com on Thursday that Oswalt also is very interested in returning to Philadelphia. It is not a stretch to think that if something happens to one of the Phils' starters that Philadelphia general manager Ruben Amaro Jr. would sign Oswalt as a replacement.

Amaro did it once before, signing Pedro Martinez during the middle of the 2009 season.

Hitting foremost on Manuel's mind this spring

CLEARWATER, Fla. -- Charlie Manuel is setting a clear tone for his hitters in Spring Training.

The Phillies manager talked with Jimmy Rollins for more than 15 minutes in his office Thursday, on the eve of the team's first full-squad workout Friday.

"We talked about how we wanted to play, we talked some about hitting," Manuel said. "It was good. Jimmy's always been a good student as far as knowing how to play the game and all about the game, and I felt like before we got going here that I would want to sit down and talk to him."

Manuel wants his team to take a better approach at the plate, and he wants his hitters to talk more about their hitting during the season. He hopes that will help the Phillies avoid the postseason offensive slumps that played a big role in ending their last two seasons.

"I want to talk to all of our guys," Manuel said. "I want our guys to talk about hitting. I want guys like Chase Utley and Jimmy Rollins and [Ryan] Howard and [Shane] Victorino ... I want to have more talk about hitting, talking about getting good balls to hit, not giving away at-bats, things like that.

"With our pitching and everything like that, we need to score the runs that we're supposed to score. If we have a guy on third base with less than two outs early in the game, we need to score one run. If we have two guys on, we need to make sure we score one run, instead of a guy standing there maybe trying to bust the game open."

Manuel also confirmed Rollins will be his leadoff hitter this season, which is not a surprise.

Worth noting

• Phillies left-hander Cliff Lee did not throw a bullpen session Thursday after throwing Tuesday. "He's just stepping back a little bit," pitching coach Rich Dubee said. "He's pretty much where he needs to be. He's stepping back. He's got extra time before he gets into the game."

• Right-hander Jose Contreras is scheduled to throw his second bullpen session Friday. He is recovering from right elbow surgery.

• Phillies position players had to officially report to camp Thursday. Everybody showed. The team holds its first full squad workout Friday. The Phils play an exhibition game next Wednesday against Florida State before opening the Grapefruit League schedule March 3 against the Yankees at Bright House Field.
