Nathan threw a breaking ball that nearly bounced and that catcher A.J. Pierzynski had to reach for. Seemingly rightfully so, Zobrist headed for first base. Then Foster punched him out to end the game and give Nathan his milestone.
Then Zobrist flipped out. Then Rays manager Joe Maddon flipped out:
After the game, Maddon was still flipping out (OK, he didn't flip out, but safe to say he won't be getting an invite to the umpires' ball this winter):
For what it's worth, Foster admitted after the game that he blew the call, saying, "I saw the pitch [on replay] and of course I don't have the chance to do it again. But had I had a chance to do it again, I wouldn't call that pitch a strike." FanGraphs.com shows you just how out-of-the-zone that pitch really was.
