I would guess that opposing teams are going to give him the steady diet of off-speed and breaking slop that most young players get fed in their first exposure to the big leagues.Hopefully it will take a few weeks for pitchers to get a book on him. He might be better in the short term than you think.
We should be prepared for him to swing and miss, a lot. Hopefully, a couple pitchers are dumb enough to throw him a hittable fastball. I kinda doubt it, though.
Hopefully, he doesn't go 0-for-the rest of the season and can make use of this experience next season in the minors.
