Wheeler (elbow) threw off the slope of the mound Monday and will next progress in the next few weeks to a tossing a full bullpen session, ESPN's Adam Rubin reports.
No timeframe has been set yet for Wheeler to toss a bullpen session. But he has progressed steadily from stage to stage in his rehab, save for a slight setback to remove a stitch in his elbow in April. All signs currently point to a July 1 return, thought that's dependent on no setbacks.
