It could become a bigger problem as the pennant race heats up.
"This time of year it's difficult to make those kinds of moves," said Phillies assistant general manager Scott Proefrock, when asked about making a trade to bolster the bullpen. "We're always looking to make the club better, but I think Antonio has pitched very well at Triple-A. He's shown he's capable of getting outs at the Major League level. Absent last evening and absent J.C.'s mechanics, we've got two left-handers in the bullpen we've had success with at the Major League level."
Romero, who had surgery last year on his left elbow, clarified some comments he made Tuesday, when he indicated he might be injured.
He said he is healthy.
"My arm is fine," he said. "At the beginning, when I was on the DL, I had no arm speed. It was easy for my hand to catch up. Now my arm is faster and my hand isn't following it the right way. I'm not coming around the ball. ... It's hard. It's like you hesitate to let it go. I've got realize I'm healthy so I've got to start being aggressive and start attacking the strike zone."
