According to MLB.com's Corey Brock, an MRI on Tim Stauffer's right elbow revealed no structural damage. Manager Bud Black said it will be ''a few days'' before Stauffer is allowed to pick up a ball, as the Padres won't risk him taking the mound at less than 100 percent. The 29-year-old right-hander should be cleared to make his 2012 debut by mid-April.
