I think the 4 out thing is going to be Hinch's contribution to future std practice. Old conventional wisdom was to avoid the up and down, but bring a guy in to get the one out, he's mentally more ready to start the ninth.
EDIT: OK, no coal for Riley
Man, he's had more than one high stress inning and is at 88 pitches. Do you send him back out? Probably not in the regular season, but who knows how Hinch is gaming this out.
