NEW YORK -- Bartolo Colon threw 31 pitches in a bullpen session on Friday in Tampa, Fla., the Yankees right-hander's first time on a mound since suffering a strained left hamstring.
"I heard he threw all his pitches, he threw well," said Yankees manager Joe Girardi, who added that Colon will throw a simulated game on Monday. "We'll see how he's feeling after that. Hopefully that goes well and we can continue to move forward with him."
Colon, 37, was injured in a June 11 start against the Indians at Yankee Stadium. After making the team as a non-roster invitee, Colon started the year in the bullpen but moved to the rotation when Phil Hughes went on the disabled list in April.
At the time of the injury, Colon was 5-3 with a 3.10 ERA. His spot in the rotation has been filled through two starts by right-hander Brian Gordon, who served up three home runs -- two to Chris Heisey -- in his losing outing on Wednesday against the Reds in Cincinnati.
Girardi has said that he expects Gordon to make another turn in the rotation. Colon is slated to throw about 50 pitches in Monday's simulated game, and Girardi said that Colon would need to be able to get through the equivalent of six innings before the Yankees would activate him.
"We have to make sure he can cover bases," Girardi said. "We have to make sure he can make quick, sudden stops and starts if they do some stuff on him. He is a good fielder and he reacts quickly off the mound, so we have to make sure he can do that. We have to see how he throws and to see if he's favoring it a little bit."
