MINNEAPOLIS — Vladimir Guerrero has a torn muscle in his chest and will miss at least a month.

The Angels sent the slugger to Los Angeles on Friday to be examined by noted team orthopedist Dr. Lewis Yocum, who found Guerrero's pectoral tear. An MRI test the day before showed a strain.

Manager Mike Scioscia said before the game at Minnesota that Guerrero would be re-evaluated again in a month, but expressed optimism for his recovery and said he can heal without surgery. Guerrero hadn't played in the field yet; he has only been the designated hitter and is batting .250 with one home run and three RBIs.

Scioscia said Guerrero's replacement on the roster would be revealed after the game. Maicer Izturis was the DH on Friday, batting third.
