That's sort of irrelevant. They were called balls. And they were hardly center cut fastballs. Sometimes you don't get the corner. Even then, Arrieta had retired 7 straight and wasn't laboring, having him start an inning with 90 pitches against the bottom half of the order is perfectly fine. this is meatballish but i think arrieta's confidence is kind of wavering these days. i'd have loved for him to exit the game with a clean scorecard and then hand it over to the bullpen of doom. now he goes into his next start knowing when he's sharp he can still let the game get away from him a bit.
