Tim Stauffer (elbow) threw his first bullpen session Monday since landing on the disabled list in May. It went well," said Padres manager Bud Black. "His motion looked good." Stauffer will throw another bullpen session Wednesday before heading to Arizona to begin a minor league rehab assignment with the Padres' Arizona League team. The 30-year-old right-hander could return to the Padres' rotation later this season.
