TRAINER'S ROOM

Padres: RHP Robert Stock was optioned to Triple-A El Paso to make room on the roster for Strahm. ... OF Franchy Cordero (right elbow strain) left Wednesday's rehab assignment with a left leg injury. "Still waiting on a full rundown of where he is today," manager Andy Green said. "He tweaked the quad yesterday, wait and see how he responds to that. You don't typically know about those things until you get a couple of days faster."

Rockies: Activated LHP Mike Dunn from the 10-day injured list and optioned LHP Phillip Diehl to Triple-A Albuquerque. Dunn missed just 10 days with a left A/C joint inflammation.
