NEW YORK -- Carl Pavano made his second rehab start on Friday night, leaving after 63 pitches with tightness in his right biceps.
Pitching for Double-A Trenton against Bowie, Pavano allowed one run on three hits in six innings, striking out six without issuing a walk. Pavano had been scheduled to throw about 90 pitches in the outing.
Rich Monteleone, the team's special pitching instructor, was at the game monitoring Pavano, and he made the decision to cut Pavano's night short.
"Monty said that although he was throwing well, his bicep was getting a little tight," said general manager Brian Cashman. "Monty pulled the plug; he wanted to be cautious."
According to Cashman, Pavano remains on schedule to make his next start on Wednesday.
"He threw well," Cashman said. "He'll prepare for his next start in five days."
Pavano said that the soreness was essentially the same thing pitchers go through in Spring Training. Pavano threw just two innings during the spring, so his current rehab assignment is his form of Spring Training. He is expected to make at least two more starts before rejoining the Yankees, assuming this latest setback does not become an issue.
"If I had gone into Spring Training healthy, I would have gotten 25 to 28 innings," Pavano said. "Right now, I'm at 17. So I think it would make no sense for me to cut myself short."
Pavano, who missed the second half of 2005 with rotator cuff tendinitis, missed most of Spring Training with a balky back.
"I made some great pitches," Pavano said. "My location was good, my velocity was good; I felt good. I was supposed to throw a few more pitches than 63. But Monty said 'That was it.' Every time out, I'm extending myself a little more.
"I think it was definitely a step better than the last one, and I expect the next one to be the same."
