Ibanez went 0-for-2, walking in his second plate appearance, scoring a run and successfully converting his only chance in left field.
General manager Ruben Amaro Jr. made the trip to Reading, so he was unavailable to reporters. But he did speak with Philadelphia manager Charlie Manuel about Ibanez's progress.
"According to what Ruben said, he was still [feeling] OK when they took him out of the game," Manuel said.
Ibanez will play six to seven innings in another rehab appearance Tuesday with Triple-A Lehigh Valley. The 37-year-old is then slated to rest on Wednesday before playing in the Minors again Thursday.
"We'll go from there," Manuel said.
If Ibanez feels good, he could be activated to play against the Pirates this weekend.
Ibanez -- named to his first career All-Star team on Sunday -- was hitting .312 with 22 homers and 59 RBIs before landing on the DL. Manuel, who will also manage the National League squad at the July 14 Midsummer Classic, does not know if his star outfielder will be ready for the trip to St. Louis. But he has a hunch.
"I haven't talked to him about those things," Manuel said. "But more than likely if he's going to play before the All-star Game, he'll probably want to play in it, because he's really excited about being picked."
