Ramirez (thumb) heads to disabled list

The Chicago Cubs placed third baseman Aramis Ramirez on the disabled list Wednesday with a left thumb contusion.

ESPNChicago.com's Bruce Levine reported Tuesday that the move was forthcoming, and as expected, Chad Tracy was called up from Triple-A Iowa. Tracy is hitting .396 with five home runs and 18 RBIs with Iowa.

Ramirez, who's hitting just .168 with five homers and 18 RBIs, has been battling the injury for the past two weeks. He missed 80 games last season.
