Yep - The guy is a phenomenal athlete. But he's got to watch some film and figure out what he's doing wrong at the plate. Pitchers have seen a weakness they're exploiting and he hasn't made the adjustment - yet.
Yeah, I really feel for Jac, this learning curve was steeper than any of us saw coming, but he has raw talent and just needs to work through it. It might mean a demotion back to AAA, because at some point he needs to get some production and keep his confidence. But hopefully, he will have a good series coming up and change this negative momentum.
