Win/Loss doesn't matter that much in the grand scheme of things, the decisions made could've ended up being fine if Devin gets one grounder for a double-play.
With that said, it seems to happen all of the time...
Using the DEV(in)CON scale:
DEV(in)CON 5: Fatigued star closer gets asked to close out another game.
DEV(in)CON 4: Said closer's command just a smidge off, HBP followed by a sharp double
Event: Manager's undies bunch, says to self, "He's our indomitable closer, it's his game no matter what."
Event: Closer shows signs with a K. Manager feels better
DEV(in)CON 3: Long AB, leads to walk, fatigued closer now at 17 pitches. Fans' undies bunch.
Event : Star closer gets another K. Two down. 23 pitches. Just. One. More. Pitch/Out. Still a two-run game.
DEV(in)CON 2: Star closer gassed. 4 pitch walk. Run scores. 27 pitches. One run game. Now or never.
DEV(in)CON 1: 8th consecutive ball. Disaster imminent.
I disagreed with Murphy's decisions. I feel like Megill, being fresh, needed to be ready to go in at DEV(in)CON 3. Not just for Devin's sake, but for Megill's. It isn't fair for him to have to clean up the mess left over by Devin on his first appearance back.
If accurate, I still disagree, but I think the only two explanations are (1) Murphy screwed up. Didn't have Megill ready in time, or (2) Murphy wanted to challenge Devin. He needs to know if Devin has "it" to go on when fatigued, or have to go long in the playoffs. I suspect that Murphy won't challenge Devin the same way going forward.
