MLB Network insider Ken Rosenthal on Monday spoke to Angels general manager Billy Eppler, who said, "There have been no changes in [Shohei] Ohtani's diagnosis and neither our physicians nor medical staff have recommended [Tommy John surgery] or said it's likely."
On Sunday night, ESPN's Pedro Gomez reported on SportsCenter that Ohtani will "probably" need elbow surgery, which would force Ohtani to miss the rest of the season and likely keep him off the mound for all of 2019, though it's possible he could return to serve as a designated hitter sooner than that, as the timetable for hitters returning from the procedure is shorter than it is for pitchers.
