Halladay threw 57 pitches in a simulated game Friday and might return for Tuesday's game against the Chicago White Sox.
"That's what I would like to do if everything goes well," Halladay said. "I feel like I could pitch in a game right now. I feel fine throwing. It's just a matter of being able to field my position."
Halladay will test his fielding on Saturday. If he can't go Tuesday, he expects to pitch at home against the New York Yankees on Aug. 6 or 7.
The 2003 AL Cy Young Award winner was struck in the left shin by a line drive off the bat of Texas' Kevin Mench on July 8. He is 12-4 with a 2.41 ERA and was expected to be the American League's
starter in the All-Star Game before he was injured.
The original prognosis had him missing four to six weeks, but Halladay's leg has healed quicker than expected. He bought a hyperbaric (oxygen) chamber to help with the recovery.
Toronto general manager J.P. Ricciardi said Halladay could pitch now if it was the playoffs. Three X-rays on the bone showed it was completely healed.
"Unbelievable optimistic, we'd love to him on Tuesday," Ricciardi said. "I think worst-case scenario we'll see him in the Yankees series."
