I kinda want to defend Williams here. Even though I disagreed with his call to pull Zimm and insert Storen given the situation, I certainly don't think he (and as a byproduct Storen) deserve all the anger and hate their getting.
Yes, the move backfired, and that's hard to watch as a fanbase. It's made even harder by both the recent dominance of Zimm, but more by the memorable collapse of Storen previously.
Zimm did not look great in his walk to Panik. He was squeezed in the zone early, but it appeared to rattle him a little bit and his next few pitches were way off. Williams knew this game was a must win for his team, and he had a closer in Storen who had been absolutely lights out down the stretch. Zimm pitched an amazing game. So did Kershaw for the Dodgers until he blew up.
Storen did not fail his manager or his team. If asked, I'm sure he would make the same pitches a second time through to the same hitters. Posey stretched out and flipped the head of the bat at a pitch away, just managing to make enough solid contact to dunk it into shallow left center. It wasn't driven, and Posey didn't have much balance in his swing. Sandoval fell behind in the count himself, before putting on a Pablo'esque swing (off balance as well, ball off the plate) to punch one barely fair down the line.
Storen got unlucky. Good hitters hit good pitches. Nothing more. Nothing less. To demonize Williams for going with his closer, someone that he MUST have complete trust in, in a game his team MUST win, is really unfair to him. Likewise, to demonize Storen for getting beat on good pitches just because he had a meltdown in the past does him a disservice.
Would I have kept in Zimm? Yes, absolutely. But I can't fault Williams for the choice he made.
