I never suggested to do both with Morales. I agree, you either bring the infield in or you set up the double play, not both. With that being said, I understand that his thinking was probably not to put more runners on base, but with the way Pineiro is pitching, he just could not afford to let the Angels score again. Couple that with the fact that the bottom of the order is due up, and the chances of a big inning are greatly diminished even with an extra runner on base.
I brought up him not bringing the infield in to help illustrate the point that Joe wasn't concerned with that runner at third, which he should have been. If he didn't want to walk Morales, which would have been the proper move, he should have at least brought the infield in, especially once the count went to 1-2, when the chances to solid contact aren't good.
As for pitching Aceves yesterday, you're right, he's a multi-inning reliever while Robertson is a short reliever. No doubt about it. But here's the problem. If you give Aceves a weak off, there is no way you can expect him to be sharp in a close game, which is what they needed today. The ninth inning of yesterday's game presented an opportunity to put a pitcher out there that needs work, and if he isn't sharp it won't cost you the game. I believe it's very unlucky, although I admit that we don't know for sure, that Aceves facing a few batters yesterday would have any impact on his availability today. But the thing is, even if he wasn't available today, it would be a better situation than throwing him today after having a weak off. They would have been better off going to someone else in a close game than him, after having pitched once this year (which was a weak ago).
He has done the exact same thing with Marte. Marte has only faced two batters this year, during the first two games of the season. After Park had gotten the first two hitters out in the top of the eighth inning yesterday, the proper move would have been to go to Marte against Morales, turning him around to his weaker side. Marte needs the work, especially when you consider that he wasn't sharp in either of his first two appearances. It's impossible to expect him to come in tomorrow and get someone like Bobby Abreu out in a big spot, or Josh Hamilton over the weekend, without having an opportunity to work the kinks out.
In games where the outcome isn't in doubt, a manager has to make decisions, not just for that game, but for future games. Joe has failed to do this, and it's something that cost him today, and will continue to cost him in the future if he doesn't correct this issue.
