Manager Torey Lovullo said Ginkel (elbow) played catch Sunday with no issues, Alex Weiner of ArizonaSports.com reports.
An elbow injury apparently cropped up in early February, but the right-hander's relatively quick return to throwing is an encouraging development. It'll probably be a little while before Ginkel is cleared for game action, but at this point Lovullo expects his setup man to be ready by Opening Day.
