Scherzer (back) revealed Friday that he received a cortisone injection in his right thumb after undergoing additional tests Wednesday, Evan Grant of The Dallas Morning News reports.
The exam revealed that Scherzer's thumb issue is more nerve-related than skeletal, and the right-hander noticed significant improvement following the injection. Scherzer noted that he passed multiple strength tests that would have indicated a ligament issue, and his rehab plan has changed accordingly. The 39-year-old was on the field Friday playing catch for the first time since having his program delayed due to issues with his right thumb and forearm.
