Before 2012, Uggla was considered one of the best hitting second basemen in the league. He's a three-time All-Star and has hit 30 or more home runs in a season five times. His best year was 2010, when he hit .287 with 33 home runs and 105 RBIs for the Marlins.
The Nationals have been searching for a second baseman since Asdrubal Cabrera became a free agent this offseason.
