Yes, now, do it as fast as possible. Not only do you have Cabrera, but with the depth at 3B, LaRoche probably won't be much more than a 4th rounder anyways, and that's still too far away to predict. Cain is only 22 (!), and he has great stuff and can easily go on runs of dominance, wait until he can consistently keep his BB per 9 between 3 and 3.5.
