The poster, if you're curious, is Cain's agent.
I have to say, this is very surprising. Cain needed to be promoted and was blocked by Cole Gillespie and Matt LaPorta at AA, but both of those players are older than Cain, and I expected one of them to get the bump to Nashville. Obviously the team values keeping the winning core together down in Huntsville.
You can find Cain's current and career stats, as well as his current splits, on the Prospects sidebar on the right-hand side of the page.
