Mark Reynolds has an 11 million dollar option for 2013 and I think it's safe to assume that the O's will take the 500k buy out option. I don't think the O's will reinstate Davis at first and there really isn't a true first baseman in the high minors with the potential to be an everyday major leaguer.
I like Townsend but he's not close to ready for next year and he can't stay healthy. I like Mahoney but I don't think he's our future there.
As far as free agents are concerned...here's a list of the first basemen who's contracts end after this year. This list could grow as some options are declined.
Lance Berkman
Carlos Pena
Adam Laroche (has a 10 million dollar option with a million dollar buy out - likely could be available as well)
James Loney
Aubrey Huff (also has a 10 million dollar option....I don't see that getting renewed though)
Carlos Lee
The other interesting name here is Mike Napoli who can play some first and is a free agent after this year as well. Will Texas be okay with letting him walk now that they have Soto on hand?
Justin Morneau could be available through a trade still and I think the Twins are interested in moving him. I see him going in the off season at some point.
None of these free agents are that interesting to me as this list is mostly peppered with over the hill power hitters who aren't middle of the order threats anymore especially in the AL East.
