I think he will be. The only concern I have for him is whether he can get over the blown save or not.
I'm not too concerned about that. When he hears the standing ovation the home crowd will give him when he is introduced on Opening Day, crapting himself on the mound in game 5 will be a thing of the past. If he's such a mental midget that he can't get past it then we just need to move on and find someone else to close. We don't freaking have time to be coddling the weak minded. We have to win championships.
I think he'll be fine. Thankfully he has people around him that can help him move past this. And hopefully he'll just come back with something to prove.
Just don't pitch him 3 days in a row again 
Or he can just sack up and atone for it in next year's playoffs.
