I think the idea that AAA doesn't prepare you for 95+ pitches is an odd one (side note, junk pitches are rarely in the 90s as they are off speed pitches). Sure, you won't see very many major league curve balls in AAA, but you'll see more of them there than you will in AA, A+, and A ball. I don't think anyone disagrees that major league pitching is better, but looking at Buxton and Kepler, I don't think it's an accident that the prospect who spent more time in the high minors is having more success right now in the majors. That's my biggest beef with the Twins handling Buxton. He got added to the 40 man before he was ready, and they've now burned 2 options. He's still rather clearly not ready and next year is his last option (which at this point I suspect they will need). I get sick and tired of hearing how Buxton isn't Hicks or Buxton isn't Arcia, but it is that same type of mismanagement that put the team in the position to have to deal with Hicks and Arcia in the manner that they did. Buxton needs to return to AAA and get those at bats, and he needs to do it sooner than later. In 2018, there will be no option to yo-yo him.
