It makes sense. It's an upgrade of the bench. He gives the team not only better quality depth, but also better insurance in case one of our infielders hits the DL. He is good enough to be a starter, if it came to that. Plus, he's a right handed bat.
Personally, I've always liked Hill.
I understand the concern about giving up starting pitching depth. The point made about how having Miley as additional depth would have helped the team, even if he isn't pitching that great, is valid.
Dombrowski isn't stupid. This move all but guarantees starting pitching is coming our way soon, and probably more than one starter.
It's not a huge move, and I'm not crazy about giving up Wilkerson, but I like the move overall. I like the addition of Hill to the team.
