Not sure how sarcastic/rhetorical this is (all good no matter the answer), but I thought it was a good question in terms of Sproat, and it got me thinking.
Sproat's issue has really been the walks, the inability to harness the stuff and to reset after giving up baserunners or experiencing bad batted ball luck. If this is about "stuff," then it's maybe a good thing, assuming May can command his stuff better, which it seems like he can.
On the other hand, if May has Sproat's stuff and better command and still can't get results, maybe we should re-evaluate our assessments of Sproat's talent too.
May seems like a one time through the order guy in the postseason to me. That's not a bad guy to have in that role. But, obviously, there's plenty of reason to be concerned.
My reason for optimism is this: if the Brewers bullpen continues to pitch this well, all we need is Gasser and May to be serviceable.
