I'm surprised about the Cooper move. He isn't an exciting player by any means, but I would say he has been about what he was expected to be and did fine in a limited role.
I think this move says more about the Cubs' confidence in Busch than anything else. Cooper was insurance in case Busch didn't take off right away, but clearly Busch isn't going anywhere. Plus, with Wisdom also able to fill the right handed corner infield role, Cooper became even more redundant.
I hope Mervis has success this time around, He earned another shot, but I still don't think the Cubs have a lot of faith in him as a Major League player.
