A’s right-hander A.J. Griffin’s recovery from Tommy John elbow surgery has been shut down after he experienced shoulder soreness during a simulated game Thursday.
Joe Stiglich of CSNBayArea.com reports that the A’s are hopeful it proves to be a minor setback because Griffin hadn’t previously dealt with any shoulder problems.
He was close to being cleared for a minor-league rehab assignment about a year removed from surgery, but now Griffin’s recovery timetable is on hold.
Prior to the elbow injury Griffin started 47 games for the A’s in 2012 and 2013, posting a 3.60 ERA and 235/73 K/BB ratio in 282 innings. He missed all of 2014.
