“When he was warming up several days later for another session of live BP, he felt some discomfort. We shut him down. We had some MRIs done. There was new damage that had occurred to the ligament.”MORE: Watch ‘ChangeUp,’ a new MLB live whiparound show on DAZNThe No. 2 overall pick in the 2017 MLB Draft, Greene, 19, was 3-7 with a 4.48 ERA for low Single-A Dayton last year before being shut down because of a sprained ulnar collateral ligament. The Reds hoped he could return by rehabbing his elbow instead of undergoing surgery. Instead, almost a year later, he’s now facing the ligament-transplant procedure.“Everybody was on board with what we did. We wish it had worked Now that it hasn’t,” Williams said of delaying surgery in hopes of avoiding it altogether. “It was clear from the scans that surgery would be required to make sure we get repaired.” Right-hander Hunter Greene, the Reds’ top pitching prospect and No. 36 in MLB Pipeline’s Top 100, will undergo Tommy John surgery next week, the team announced. “He’s been examined by our doctor and Dr. (Neal) ElAttrache,” Reds president of baseball operations Dick Williams said (via the Cincinnati Enquirer). “They’ve been working on this in the past. He had a setback last week. He threw to live hitters last Saturday. I was there. The session went well. Thanks for all the❤️ I’m in great shape & great spirits. I’m in LA & will have surgery next week by Dr. Neil Elattrache. I have an amazing support group & people around me that will make me even stronger. I’m still on track, time to move forward!— Hunter Greene (@HunterGreene17) April 2, 2019Greene — who as a 17-year-old high schooler was talked about as “baseball’s LeBron or the next Babe” — appeared upbeat Monday on Twitter after the team’s announcement, which means he’s likely facing a 12- to 15-month rehab.”I’m in great shape (and) great spirits,” he tweeted, adding, “I’m still on track, time to move forward.”COVER STORY: Hunter Greene is the star baseball needs.
