On one hand, a no hitter seems like a very real possibility. On the other hand, maybe if he gives up a hit, he'll unravel a bit. Anecdotally, that feels like that happens in situations like this.
I think this ump has gotten every close call correct. Even the one the Marlins' catcher dropped. It's refreshing
Edit: ope strike 1 to Busch was bad. Nvm
