Easy to blame Tito for this one, but every now and again a manager runs into a situation where he makes the right move over and over again and it doesn't work. That was tonight.
Even if he was tired and it wasn't the smartest move to chance Masterson for a third inning of relief, he's still a talented pitcher -- he should have struggled, maybe let up a run or two, and then got out of it. Besides, he was rested, although perhaps that was part of the problem, since I noticed that he was throwing very hard in his first 2 innings of work and maybe the sinker just wasn't there for him when that wore off.
Also, both Oki and Saito should have been their usual, effective selves. You can only blame Tito so much for trying to leave guys in for extra innings when the starter was only able to go 4 innings. And you can't blame him at all for going to dominant relievers who somehow don't get the job done this time.
File this one more under "ideas that made sense or at least should have worked out better than they did."
