CLEARWATER, Fla. -- Right-hander Andrew Carpenter's future is no longer in the rotation.

The Phillies are making him a reliever after clearing waivers Sunday and rejoining camp Monday. The club designated Carpenter for assignment last week to make room for right-hander Brian Schlitter on the 40-man roster.

"We'll try to simplify some things," pitching coach Rich Dubee said. "Get him back to a fastball, cutter, split guy. We think he has enough stuff to get through a lineup one time. Getting deeper was maybe a little too difficult."

Carpenter is 1-1 with a 9.31 ERA in five appearances (one start) with the Phillies. He is 45-35 with a 3.71 ERA in 109 appearances (104 starts) in five seasons in the Minor Leagues.

"We feel like this is his best chance to be a productive Major League pitcher," Phils general manager Ruben Amaro Jr. said. "His split might give him a big of an edge as a bullpen guy."

Doc on schedule to start season opener April 1

CLEARWATER, Fla. -- Phillies pitching coach Rich Dubee pinned the pitching schedule to the bulletin board just inside the clubhouse Monday afternoon at Bright House Field.

The way it looks, Roy Halladay will be the Opening Day starter April 1 against the Astros at Citizens Bank Park.

That is no surprise.

The rest of the rotation -- if it remains in order -- should be Cliff Lee, Roy Oswalt, Cole Hamels and Joe Blanton. Hamels is scheduled to start the Grapefruit League opener Saturday against the Yankees at George M. Steinbrenner Field in Tampa, Fla. Also scheduled to face the Yanks are Vance Worley, Ryan Feierabend, Brian Schlitter and Mike Zagurski.

Blanton will take on the Yankees on Sunday in the home opener at Bright House Field. Also scheduled to pitch Sunday are Justin De Fratus, Michael Schwimer, Ryan Madson, J.C. Romero and Brad Lidge.

Halladay is scheduled to pitch Monday against the Blue Jays in Dunedin, Fla. Lee is scheduled to pitch March 1 against the Tigers at Bright House Field. The schedule is not posted for the March 2 matchup with the Orioles at Bright House Field, but Oswalt is expected to start.

But before the Phillies open the Grapefruit League schedule, they play an exhibition game Thursday afternoon against Florida State University. Dubee said Drew Naylor will start. Eddie Bonine, Juan Perez, Michael Stutes, Schwimer, De Fratus and Scott Mathieson also will pitch.

Hurlers throw BP, while hitters track pitches

CLEARWATER, Fla. -- Phillies pitchers threw batting practice to hitters Monday morning at the Carpenter Complex, but it was no laser show.

Hitters typically do not swing the first day because they are tracking live pitching for the first time since last season.

Roy Halladay faced Chase Utley, Raul Ibanez and Brian Bocock. Nobody swung at a Halladay pitch, although Halladay grazed Bocock with one ball.
