Hoskins struggled for one month at Williamsport, then hit at every level, home and away, the next three years. He's been underrated b/c he's a RH 1B and a 5th rd pick out of college.
He's not going to maintain this pace, but yes, he's for real, he's going to be at the center of the lineup well into the next decade.
As he's shown in LF, he's a better athlete than expected, he could actually be a credible LF with an offseason to work on routes and picking up the ball off the bat, but 1B is his future given the OFs in the system (though Derrick Hall might change that if he rises rapidly next season).
