I've been a proponent for Achter, in preference to signing guys like Boyer or not trading away guys like Fien. However, I hadn't looked at Rochester FIP numbers on Fangraphs until now, and Achter's nice ERA looks like it may be something of a mirage by this measure. 3.69. Even guys like the maligned Mark Hamburger have more favorable FIP. I'm not 100% sold on FIP being the ultimate projection tool, but maybe the AAA on-field staff are seeing the same things that FIP is trying to say, namely that he isn't having a standout season at this level and probably would not be a net positive asset if he were brought up?
