Padres manager Mike Shildt said Monday on 97.3 The Fan that Darvish (elbow) threw a simulated game Sunday which included three "up and downs."

Shildt added that Darvish recovered well from the session and the next step will either be another simulated game or perhaps a rehab start. Darvish was recently shifted from the restricted list back to the 15-day injured list, but he's considered healthy and it's all about rebuilding his stamina at this point. There should be more clarity on a potential timetable later this week.
