On Monday, the Cincinnati Reds announced pitching prospect Hunter Greene needs Tommy John surgery after he suffered a setback in his elbow.
Greene is just 19 years old, but injuries have already been a dominant storyline early in his career. He sprained his UCL in August and missed the rest of the season but elected not to undergo surgery at the time and instead strengthen it as he looked toward the 2019 campaign.
"The positive, if there is any such thing, is that if it happens now when he's 18, he'll still only be 19 and ready to go," then-Reds interim manager Jim Riggleman said at the time, per Kyle Melnick of MLB.
