As teams consider sending prospects to the Florida Marlins for Miguel Cabrera, some have raised concerns about the third baseman's fitness. But Cabrera, who along with Johan Santana is expected to be one of the most highly-sought names at baseball's Winter Meetings, has reportedly been working out during the offseason to address those concerns. "He looks good," said Los Angeles Angels' catcher Mike Napoli, who has been training with Cabrera for the last three weeks, according to the Los Angeles Times. "He's starting to slim down, and he's getting real strong." Chicago White Sox Manager Ozzie Guillen, who saw Cabrera in Miami on Sunday, said the third baseman "has lost about 15 pounds maybe a little bit more," according to the Times. "If you see Miguel Cabrera now, you will be surprised."
