Webb threw around 35 pitches Saturday, half from the windup and half from the stretch, and declared himself ready to pitch in a Major League game.
"From my standpoint, I feel I'm good to go," Webb said. "Obviously, I'm not in midseason form. I think once I get into a real game, the adrenaline would carry me that much farther."
Webb said he will sit down with Towers, who was hired last week and is in San Diego this weekend tying up some loose ends, on Monday in Phoenix before the team departs on its season-ending road trip.
"I know I'm not 100 percent," Webb said. "I don't think I need to be 100 percent, midseason form to go out there. So hopefully we can see eye-to-eye on that and do it. I'm looking forward to sitting down and talking about it with them Monday."
Webb will be a free agent at the end of the season and obviously would like to show teams that he is on the road to recovery from shoulder surgery last August. He has not pitched in a game since Opening Day 2009. He was asked if he thought the team was less inclined to get him in a game and help him increase his value for next year.
"Possibly," he said. "I don't know. That's what we'll get out of Monday. Just get their feeling for what they have in store for me."
