Roy Halladay pitched in a competitive situation for the first time since May 5 when he worked six innings for the Phillies’ Gulf Coast League team in Clearwater Fla. on Thursday.

Pitching against Pittsburgh’s rookie league club Halladay who had shoulder surgery in mid-May allowed six hits and three runs. He walked three and struck out four. He allowed a solo home run in his final inning of work and threw 87 pitches.

Physically Halladay came out of the start feeling good. He is slated to throw a bullpen session in Philadelphia on Saturday and will make a second minor-league rehab start on Tuesday at a yet to be determined site.

Halladay’s fastball was 85 to 87 mph according to a witness. The right-hander will need more pop than that to get major-league hitters out.

“I spoke with Roy and with people who were there to evaluate him and they feel that he continues to make progress” GM Ruben Amaro Jr. said. “He is not as crisp as he wants to be yet. It is likely that he will have at least one more rehab start. He is scheduled to throw a bullpen in Philadelphia on Saturday and we’ll know where he will pitch on Tuesday once he completes that session.”

Amaro is on record as saying that Halladay could make as few as two rehab starts. If that turns out to be the case he could be back in the rotation in the final week of August.
