Halladay remains positive about his chances for returning to the mound, less than three weeks into a six-to-eight week rehab period. Halladay is expected to begin throwing again in July, but acknowledges the possibility for setbacks.

"In my mind there's no doubt that I won't be back this year," Halladay said. "It's a week-to-week process. There could be bumps in the road but as of right now, I don't see any reason why I shouldn't be back this year."

Halladay is set to return to the team's spring training complex in Florida in the coming days. 

"Rehab has been going very good," Halladay told reporters, per The Philadelphia Inquirer. "Good, I’ve been good. Obviously the surgery was what we thought it was. So far the rehab has been very good. Very good."

Halladay said he's getting back into leg strengthening and he's impressed with how different he already feels post-surgery.

"It feels good. I’m excited," he said. "We can’t give timetables, because at this point it’s a week-to-week process. We set up a plan based on how the last week went and what we want to accomplish the next week and we go from there."

Halladay is expected to be out until at least late August. 

"That’s very possible," Ciccotti said. "The combination of a rotator cuff injury and a labral injury is a challenging injury for a professional pitcher to navigate through."

Despite that worst-case prognosis, the team was pretty happy with the results of Halladay's shoulder surgery, and thinks he can begin a throwing program in six to eight weeks.

"It’s very possible. It is very possible," he said. "Well, we remain cautiously optimistic about it. And given the person that he is, the motivation that he has, the dedication that he has, he has all the intangibles that are important in getting someone back. But we’re realistic about it, too, that it is very possible that he is not pitching at the level that he wants or what Phillies fans and his teammates deserve him to be pitching at."

Halladay's best-case scenario probably involves him returning to the mound in three months.
