According to Bryan Hoch, MLB Insider covering the New York Yankees, pitcher Luis Severino will undergo Tommy John surgery.
According to ESPN, Yankees' Manager Aaron Boone mentioned that Severino had been dealing with forearm discomfort going back to game 3 of the ALCS against the Houston Astros.
After two MRI's and a CT scan in late 2019 and early 2020, which returned negative results, the Yankees wanted further testing. Severino wasn't active until September of last year due to other issues with his rotator cuff and muscles.
Severino had little trouble throwing his fastball and slider, but his changeup caused significant forearm stiffness. That sort of injury is known to often lead to problems with the UCL (Ulnar Collateral Ligament), which can further lead to the need for Tommy John surgery. The news is not pleasant for Luis or the Yankees, as Severino will now miss the 2020 season after missing most of 2019.
Severino was an All-Star in both 2017 and 2018 and was in the Cy Young mix, winning 14 and 19 games in those years, respectively. The Yankees certainly missed his mound presence in 2019, and unfortunately will have to work around his absence this season as well.
On top of the loss of Severino, the Yankees are also dealing with injuries to pitcher James Paxton. Paxton will undergo back surgery but is expected back by May. Outfielder Aaron Judge has dealt with shoulder problems but is progressing nicely. Pitcher Masahiro Tanaka is still working through issues with a partially torn UCL he first felt back in 2014. Rather than go the Tommy John route, Tanaka decided on continual rehab - something he is still dealing with as we enter the 2020 season.
The Yankees had their hands full with injuries in 2019, and 2020 is off to a rough start for the beleaguered club as they search for their first title since 2009.
