This deal will most likely go through barring any snags and a physical. Abreu and the White Sox seem like a perfect match, where the White Sox 2013 first baseman Paul Konerko becomes a 37 year old free agent in the winter. Don't be surprised if Abreu doesn't take the major league job immediately, but could take it pretty soon. Since a deal wasn't completed during the season, Abreu will most likely have to wait to get some MiLB at bats next year, unless he impresses very much during Spring Training.
This is a great signing for the White Sox, as they have spent their largest amount of money on any international free agent ever on Jose Abreu. I think he'll impress in the Windy City, where he will provide a lot of power in a somewhat hitter-friendly park.
