I dont think there is anything wrong. I checked everywhere i knew of and couldnt find anything about an injury. Its probably b/c of playing time for outfielders.
The Twins have unveiled a plan to squeeze seven hitters into five available lineup spots.
Torii Hunter, Jacque Jones, Lew Ford and Shannon Stewart, Justin Morneau, Doug Mientkiewicz and Matthew LeCroy will have to split up the outfield, first base, and DH duties, meaning at least two of them will be on the bench each day. Jones has already stated his displeasure about not playing every day. Manager Ron Gardenhire hinted that a trade could be on the way to remedy this issue. Hopefully the Twins can get rid of some of this excess to get middle infield or rotation help.
