Gray (back) felt healthy in a 60-pitch start Monday at Cincinnati's alternate training site, C. Trent Rosecrans of The Athletic reports.
Gray has been on the mend since March 14 due to a back issue, but he continues to make steady progress in his rehab. He'll be eligible to come off the injured list as early as mid-April, though the Reds have yet to announce when the right-hander will return to make his 2021 debut.
