Many think the New York Yankees will be just fine when Luis Severino returns to the team mid-season. That outlook may be too optimistic. Severino needed Tommy John and had that surgery in February. Players with that surgery usually can return to playing in 12 to as many as 18 months, although most return by the 15th month. The snag is there are no hard facts to support when and if a pitcher can return and how he will hold up or perform. It seems to be different for each individual pitcher.
Jordan Montgomery didn’t play the entire 2019 season after his surgery.
