BoSox hope he returns by Tuesday, or before

Boston Red Sox: Ace Pedro Martinez was still sick in bed on Friday, a day after he was scratched from his start with a sore throat and fever. The Red Sox were hoping that he would be ready for his next scheduled start.

Martinez, who was scheduled to pitch Thursday, instead went to the hospital and was diagnosed with severe pharyngitis -- inflammation of the throat. He was given medication for the fever and for the sore throat and was resting by late afternoon.

That's where he was Friday when manager Grady Little called him.

"Pedro's doing a little better," Little said. "We're very hopeful that he'll be able to make his next start."

Little wouldn't rule out pitching Martinez before Tuesday, but he wasn't counting on it, either.

"He's not even well enough to come to the park today," Little said.

Casey Fossum took Martinez's turn in the rotation on Thursday night, earning the win with four earned runs in 5 1/3 innings. On Friday, the Red Sox optioned Fossum to Triple-A and purchased the contract of Bronson Arroyo from Pawtucket.

Arroyo pitched the fourth perfect game in the 120-year history of the International League history on Aug. 10. He will pitch out of the bullpen.

"This kid Arroyo certainly deserved the opportunity," Little said.

New York Yankees: Right-hander Jon Lieber allowed one run over four innings in his second minor league rehabilitation start since undergoing reconstructive surgery on his elbow one year ago.

In a Gulf Coast League game against the Phillies at Tampa, Fla., Lieber gave up five hits -- including two infield singles -- and struck out five. He threw 39 of 47 pitches for strikes.

"It felt good to get back out there," said Lieber, who topped out at 94 mph on the radar gun. "The important thing for me is to keep going out inning after inning and how I feel each time I do that."

Lieber is slated to make another a minor league start next week.

He said team officials have not talked with him about the possibility of joining the Yankees later this season.

"The bottom line is getting my work in while I'm down here and we'll go from there," Lieber said.

Lieber went 20-6 for the Chicago Cubs in 2001. The Yankees signed him to a two-year contract during the offseason.

Lieber threw two innings in a Gulf Coast League game last Friday. It was his first appearance since pitching for the Cubs against San Diego on Aug. 1, 2002. He had surgery one week later.
