Wingeter recently underwent back surgery and won't return to pitch this season, per MLB.com.
The right-handed reliever underwent Tommy John surgery last July but was hoping to make a late-season return to the Padres bullpen. He started a rehab assignment in August but was shut down after three outings due to a back injury. Wingeter underwent a microdiscectomy in mid-September and is expected to be fully ready to go come spring training.
