After 75 pitches, though, he was all smiles.
"Those first ones, I was a little discouraged," Webb said. "For some reason, I don't even know what it was, I was still kind of short and cutting off in front and keeping it short in back. But the second set, I was just trying to keep everything long and really stretch out and reach out front, and it felt great. I went from being kind of discouraged to it went real good and I was real happy with it."
There has not been a lot for Webb to feel good about since undergoing right shoulder surgery last August. He started throwing off a mound in January, but after struggling during a bullpen session March 4, he had not thrown off a mound until this past weekend.
Webb is still trying to get comfortable with his mechanics again. He discovered in April that his arm slot was higher than it had been in the past, and that was one of the things holding him back.
On Wednesday, he did not use a full windup the entire time -- more of a step with his right foot against the rubber and throw -- but still he continues to move forward in his bid to return to action. Webb has not pitched in a game since Opening Day of last year.
Webb will play catch the next couple of days before getting back on the mound for another bullpen session this weekend while the club is in Detroit.
"I'm not even trying to throw hard, but it's coming out way better, so I feel like I've got a lot more in there, so that's encouraging, too," Webb said. "Hopefully it won't take me long, and once I get [the mechanics] down, it should go quickly."
