Then there were 2: Williams latest Phils pitcher hurt

CLEARWATER, Fla. -- Perhaps Roy Halladay could give the Phillies a few innings.

The Phils scratched right-hander Jerome Williams from Tuesday's start against the Rays at Bright House Field after he "tweaked" his right hamstring while running sprints last Sunday. Williams said he expects to make his next start this Sunday after throwing a bullpen session Thursday.

"It kind of grabbed me," Williams said. "I'm just trying to take a step back from it."

That leaves just two healthy starting pitchers in camp with previous experience in the Phillies' rotation: Cole Hamels and David Buchanan, who started Tuesday.

Cliff Lee's season is essentially finished, and his career could be as well, despite the fact he said he will try to rehabilitate a torn tendon in his left elbow a third time. Aaron Harang has missed two of his first three Grapefruit League starts because of back issues. He is scheduled to pitch Thursday.

The remaining healthy starters in camp include right-hander Miguel Alfredo Gonzalez, who converted to a reliever last season because of questions about his durability as a starter; left-hander Joely Rodriguez, who has never pitched above Double-A; right-hander Kevin Slowey, who is a non-roster invitee; and right-hander Paul Clemens, who is a non-roster invitee.

Right-hander Chad Billingsley could be a candidate at some point, but he is recovering from a pair of elbow surgeries and is not expected to be ready until late April.
