PHILADELPHIA -- Phillies left-hander Jamie Moyer is an optimist, but he acknowledged Thursday his chances of pitching again in 2010 are almost zero.

He still hopes to be back in 2011.

Moyer has a sprained ulnar collateral ligament and a strained tendon in his left elbow. He received a second opinion earlier this week from noted orthopedist Lewis Yocum. Moyer said Yocum said he does not suggest surgery.

"He's optimistic with rehab this thing can heal and heal properly," Moyer said. "I like his thinking. ... If I had surgery, it's a year, year and a half where I can't do anything. That puts me at 48 1/2, 49 [years old]. What's the liklelihood of pitching? Where am I going to find a job? But if I rehab and rehab diligently and give it time to heal -- and then prudently start rehab and take my time with it -- I'm ready to go [by Spring Training]."

Philly adds big-game pitcher in Oswalt

PHILADELPHIA -- Brad Lidge has told his Phillies teammates one thing about Roy Oswalt:

"We're getting a big-game pitcher," Lidge said Thursday at Citizens Bank Park. "I played with him for a while in Houston. He was at his best when we were playing our most important games. That's exciting to think about when we already have the stars that we do."

Oswalt, who the Phillies acquired in a trade with the Houston Astros for J.A. Happ and prospects Anthony Gose and Jonathan Villar, joins a rotation that includes former Cy Young Award winner Roy Halladay, 2008 World Series MVP Cole Hamels, Joe Blanton and Kyle Kendrick. Oswalt is 4-0 with a 3.66 ERA in eight postseason appearances.

"If he steps up like I know he can, it's going to be a lot of fun," Lidge said.

Oswalt, who makes his Phillies debut Friday night against the Washington Nationals at Nationals Park, is 6-12 with a 3.42 ERA in 20 starts this season with the Astros. Don't let the record fool you. Houston averaged just 2.51 runs per game in his starts. In his 12 losses, the Astros scored just 10 runs.

Oswalt is 3-2 with a 3.52 ERA in his career against the Nationals, 5-5 with a 3.68 ERA against the Mets, 5-4 with a 3.72 ERA against the Marlins and 0-3 with a 7.58 ERA against the Braves.

Oswalt also is a two-time 20-game winner who ranked second in Astros history in wins (143) and strikeouts (1,593). Since he made his big league debut, only CC Sabathia (149) and Halladay (147) have more wins.

"He's a competitor," Halladay said. "He goes after guys. He competes every time he goes out there."
