He has good numbers third time through, so I'm not sure the second time through criticism holds much water.
All-in-all, Houck's MLB sample size is rather small, but looking over some of our SP'ers, I like our chances with him more than them.
He'd have probably been on an innings limit, this year, but now that he has missed some time, he's probably good to go the rest of the way.
I'm not sure I'd let him go 90-100 pitches right off the bat, in is next 2-3 starts, but later on, why not?
