Bayliss, who has not pitched in a spring training game threw 20 pitches in an intrasquad game Tuesday at Pirate City. He reported no problems afterward.
"It was a real big day," Bayliss said. "Anytime it's your first time back on the mound after a couple of weeks off - it's kind of a mixture of excitement, nervousness. You kind of lost a little timing from the time that you took off."
Bayliss, a right-hander who had 23 saves and a 2.17 earned run average in 46 games for Class AAA Indianapolis last season, threw nine balls and 11 strikes, facing four batters.
"It's kind of fun to get back out there, but frustrating in the fact that, when you get injured and miss some time, you kind of fall out of your groove," Bayliss said. "Once I keep throwing, everything will come back."
The quad injury cost Bayliss probably three appearances in preseason games.
Bucs' manager Jim Tracy indicated that Bayliss isn't too far behind the other pitchers in the battle for a bullpen spot.
Bayliss feels he has catch up in a hurry.
"Yeah, I do a little bit," Bayliss explained. "Obviously the rest of the guys kind of got a two-week head start on me. The only thing I can do is just not focus on that and go out there and just try and battle. Hopefully good things will happen.
He is scheduled to pitch again in one of the games against Cincinnati on Thursday.
