That makes sense to me. I do think the Miller's current numbers aren't a good reflection of who he is as a hitter. At the same time, if he doesn't revert back to what made him successful then his major league career will be short lived. It's just not typical for such a good minor league hitter to completely fall on his face in the long run.
Actually, it's quite typical....about 70% typical.
As Bimbo points out, defenders cover more ground in MLB.
But it also needs to be pointed out that MLB pitchers don't walk batters at nearly the rate as minor leaguers do, and they are very good at taking advantage of holes in a batters swing.
Walk rates seldom go up once a prospective power batter gets to the Bigs, and K rates seldom go down.
Look at Zimmers numbers in AA and AAA at ages 22-24. See the high K rates, high walk rates, high OBP. The look at his first season in Cleveland BEFORE he was hurt. High K rate, walk rate cut in half, low OBP.
Now look at Jones at age. Almost identical.
All this excitement over bringing up the kids, all this expectation that the kids will be automatically better than what we have. Trade vets like Hernandez and Amed, because they can easily be replaced. Trade pitchers like Plesac and TMac for the same reason
This years Tribe has brought up nine rookies that have never seen MLB. We have also played five that are rookies, but had a cup of coffee earlier.
All of them were prospects that some, or even a lot of fans, touted as instant improvements, sure fire producers.
It hasn't worked out that way. It very seldom works out that way.
I'd trade a lot of them for young productive vets with control. Thats how to extract the most likely value out of the farm system. If other GMs value our kids highly, that's even better. We can't play them all, so extract some real value now.
