"I think it's like at Spring Training, because I felt strong for all 20. But there's a reason they stopped me at 20," Detwiler said. "That was the plan going in. I think they know a little better about building people up than I do. If it was up to me, I would've gone until I couldn't stand up anymore and see where I'm at then."
Detwiler's next bullpen will be on Wednesday in New York, where he will add 10 more throws that will include all of his pitches.
Before landing on the DL on July 4, Detwiler was 2-7 with a 4.04 ERA in 13 starts over 71 1/3 innings. He hopes to make an appearance before the season ends.
"I can always say I'm feeling good," said Detwiler. "But for all the coaches to be out there and see it, it shows them how I'm feeling and also shows myself that I can still locate after two months."
