Mind you, I'm still a fan of his and think he'll be a very good major leaguer. That said, he's not doing what got him to the majors and what made him a prospect. I'd be here defending him if his line were .220 / .325 / .450, and I'd be pounding the table and yelling if his line was .230 / .350 / .475.
I've seen guys, with options, not sent down and play themselves out of tough starts and stretches. However, with high K rates, that is tough to do. You can't get an extra base hit if you can't make contact, let alone hard contact. He's just a mess right now.
