He was missing up in the zone and looked fatigued, even though that doesn't compute when factoring in his pitch count. Also, since Detwiler has struggled to go late in games maybe he wanted to give Det 7+ innings of success to build his confidence.
Not saying I agree with it, but that's what I came up with for reasoning.
Hmm. Maybe it's just that Detwiler is not used to going deep into games. I wonder how many times he has actually pitched well enough to throw 100. My guess is, not a lot.
