No. He's barely 20, and is experiencing an adjustment period, as guys like Julio Rodriguez, Bobby Witt Jr, Elly de la Cruz, etc. did before him. When you pay a guy $80 mil, you have to give him every opportunity to figure it out in the majors. He's always adjusted at every step of the minors. This is just the biggest adjustment of them all, as we are currently witnessing.
I think today he put together perhaps the best 5 consecutive at-bats of his career. Worked the count, swung at his pitches, and had hard hit balls 3/5 times, with a fourth being a 3 run HR in 8/30 ballparks.
