Sale (elbow) has advanced to throwing off flat ground from 120 feet but has yet to get back on a mound, Chris Cotillo of The Springfield Republican reports.
Sale is expected to return from Tommy John surgery sometime in the middle of this season, as he underwent the procedure last March, but the Red Sox haven't offered any specific timeline. He's behind schedule due to a pair of setbacks, though neither one was arm-related, as he battled neck stiffness and then COVID-19 over the winter.
