Webb can't get loose, skips live BP session

SURPRISE, Ariz. -- Rangers pitcher Brandon Webb was scratched from a live batting-practice session on Wednesday when he could not get loose.

He is hoping this is only a temporary setback, but the Rangers are putting him on a long-toss throwing program for the time being. The club had realized Webb would not be ready before May, and this only made his immediate future less clear.

"It's tough," Webb said. "It's really frustrating for me when I'm going good and one day it's like it's pretty good, and then you have a day like this. It's a little depressing. Hopefully we'll push through it and get back on the mound again in three or four more days."

Webb was scheduled to throw at least 60-70 pitches in what would have been his fourth live batting-practice session of Spring Training. He warmed up in the outfield and then started throwing in the bullpen, but he was shut down after he told pitching coach Mike Maddux that he could not get loose.

Webb's was supposed to throw the batting practice session on Monday, but that was cut short because of rain and wind. Webb admitted he had trouble getting loose that day as well.

"I don't know," Webb said. "It's just not a good day. I didn't feel good. Talking with Maddux, even when it was raining Monday it wasn't the greatest. I said it was probably the cold weather. I don't know. I just didn't feel as good as I did the previous four times, or whatever."

Webb had hoped to pitch in a game soon, but the Rangers don't know what his next step will be. He will be examined by Dr. Keith Meister but is likely to be limited to long-toss for now.

"Talking with Maddux, he was like, 'Are you sticking with your long-toss program like we were doing,'" Webb said. "It hasn't been near as good. We haven't been doing near what we were doing when we had our own time in the pre-workout throwing stuff.

"We had tons of progress there. I had no problems at all doing that. We're going to try and stretch it out [Thursday] and get it going really good. I haven't really got it going long-toss-wise like I wanted to since we started throwing 'pens. It's just been harder."

The Rangers signed Webb to a one-year contract in the offseason. He was the National League Cy Young Award winner with the D-backs in 2006, and a 22-game winner in '08.

However, Webb hasn't pitched in a Major League game since April 6, 2009, because of a shoulder injury known as debridement. He underwent surgery on Aug. 3, 2009, to clean up the rotator cuff in his right shoulder and remove loose tissue. He did not pitch at all last season.

Webb came to camp hoping to be on the same program as other pitchers. He threw off the mound during the first workout, but the Rangers did not like what they saw. The club backed him off and put him on a throwing program. Webb went from long-toss to bullpen work to live batting practice and seemed to be progressing well until this latest setback.

"I've got a little thing on top," Webb said, pointing to his right shoulder. "I don't know what it is. It doesn't feel anything like what it was. That's good. Concern-wise, I don't know. I'm almost over it. It is what it is. I will go day-to-day a little bit and see where we're at."
