Justin Upton, Diamondbacks (bruised thumb, 4/21)
It's a basic tenet of this column: The wall usually wins. Young bounced off the wall in left center and despite the padding there and in most parks, Young's shoulder was the loser. Tests originally showed just a bruise, but "just" in this case is at the point of the shoulder, a place that's tender and fragile. Further tests showed a tear in the AC joint, which is where the collarbone and shoulder come together. The sprain is not considered severe, but he will miss a couple weeks to make sure that it heals properly. The D'backs will let him heal up, then get him back in once his throwing and swing is back to normal.
The news was better with Upton, who has a bone bruise at the base of his thumb. It's not serious, but he will need rest in order to let it heal. The D'backs used him as a pinch runner on Wednesday, which is the best indication that they think it will heal quickly. Having two guys day-to-day is a tough situation for Kirk Gibson, but the D'backs handle medical situations with the best of them.
