is two more seasons of club control after this one, whereas Wilson's contract expires and they aren't interested in re-signing him if they can get comparable results from Ryan (already signed for 2012 at $1.75M).
One of them was going to have to be the Ackley stopgap and the other was going to be the Franklin/Triunfel stopgap. Based on the contract status, Wilson was the obvious choice to move to the presumptive-Ackley position while Ryan mans the someday-Franklin-or-Triunfel position.
Especially with Kennedy hitting the ball decently, I think Wilson will be gone-gone-gone when Ackley comes up.
