Aceves is winning this poll, but I cannot see a bullpen taking further hit with him in the rotation.
We've been told he is expected to close in the event Bailey isn't performing or is hurt. He's a rubber arm guy who pitch a lot of innings, and been use a ton of back to back games. This is clearly where he fits best.
I expect the 1-2-3 to do their jobs. If they do not. Forget about it. No matter who the 5th ends up as.
