From MLBTR:
The Red Sox could soon get a good sense of the return timeline for star lefty Chris Sale. Per MassLive’s Chris Cotillo (via Twitter), Sale is expected to throw from a mound at some point in the next two weeks or so — if all goes as planned. It’s promising that he’s already nearing that milestone, having undergone his Tommy John procedure at the end of March of 2020. It is hard to imagine that Sale will be ready for the start of the season, but perhaps he could resume competitive pitching relatively early in the 2021 campaign.
