Wingenter underwent Tommy John surgery Friday, Kevin Acee of The San Diego Union-Tribune reports.
The reliever was originally prescribed nothing but extra rest by team doctors after experiencing elbow irritation last week, but the injury was evidently far worse than originally feared. The timing of his surgery means that he'll have at best an outside shot at returning very late in the 2021 season, with the most likely outcome being that he's not back in game action until 2022.
