PHILADELPHIA -- In his past five games entering Sunday, left-hander Ross Detwiler allowed one run in 10 1/3 innings and lowered his ERA to 3.89 from 4.97. The successful run started against the Brewers on June 24, when he pitched four innings in a 4-2 victory in 16 innings.
Detwiler still does not think he has a defined roll with the club, but he said he would be ready any time he was needed.
"I threw four innings there, and I throw a little more now; I kind of stayed sharp," Detwiler said. "It's one of these catch-22s where you are throwing better, you are going to throw more and you can stay sharp. But if you are not throwing that well, there are few spots you can be in."
