If you are selling now, you are losing money. The first base autos were getting around $60....whether you think he'll do anything in Cincy is moot. He will get called up and they will be selling for much more than they are now (last couple I saw were in the $20s).
I agree, the time to sell was the first 2 weeks of release. Now it is time to buy hoping for a good AAA season and a call up.
