Hanley Ramirez3B, Florida Marlins
Ramirez, who was the centerpiece of the deal that brought Josh Beckett and Mike Lowell to Boston in 2005, is one of the most talented players in the National League, but injuries and other issues led to a significant decline in his production last year. He hit .243 with 10 homers in 92 games, subpar production for a 27-year-old who was runner-up in the MVP race in 2009. With the Marlins' signing of former Mets shortstop Jose Reyes, Ramirez has moved to third base in '12. In his new position, he's hitting .265 with eight homers and 33 RBIs in Miami's first 50 games of 2012.
