Sure seems like he's ready. But two factors to consider. First, is he mentally and physically ready? Could be some refinement they're still working on with him. And since he's been in MLB already and got knocked around a little, you really want to be sure he comes up with confidence. Potentially, he's not just an option for the present but for the future as well. (As opposed to the Cravys and Blazeks, etc.) So, if you can, you want to avoid the yo-yo of going back and forth between MLB and AAA. Secondly, who does he replace? Not long ago nobody would have a problem dumping Hughes. Then he turned in a couple of exceptional outings. Every guy in the Brewers pen has had success in the past, most in the very recent past. So you want to be careful about giving up on guys too soon. If a guy lacks confidence because he got hit around in the majors two years ago after making the jump from rookie ball, he's never going to be mentally ready.
