If he can put up similar numbers to last year I don't see how it's not a good move, as they got zero production from 3rd base last year. Expect him to be on the DL at least once, but the price was right and it fills a void for them. Plus Gamel is easily going to give them .275 with 25HR and around 80 RBI, so they fill part of the run production void left by Fielder between the 2.
