Kobernus has had a rough go of things. He's been injured quite a bit, and that definitely can get in the way of your development. Then when you come back and press, it's going to hurt you even more.
He's in his first full season, and clearly, the jury is still out. Hopefully he'll pick things up as he settles in and will establish himself as a legitimate prospect.
Luckily, we have a couple guys ahead of him at Potomac(Lombardozzi) and Harrisburg(Espinosa, I know he plays SS there) that project as 2B at the major league level. We're not hurting for Kobernus at the big league level, so there is time to be patient with him.
