New York Yankees shortstop Didi Gregorius will undergo Tommy John surgery and miss part of the 2019 season, the team announced Friday.
Yankees manager Aaron Boone said he is "optimistic he'll be back at some point during the season ... a realistic chance he plays bulk of season."
General manager Brian Cashman said Gregorius had a partial elbow tear that was "asymptomatic" when he was acquired from the Arizona Diamondbacks in December 2014 to be Derek Jeter's replacement at shortstop. Cashman described the current tear as "the finishing part of something that was a sleeping giant, I guess."
