Quintana (ribs) has been cleared to begin throwing off a mound Saturday, Tim Healey of Newsday reports.
The southpaw got good news from the Mets' medical staff following a CT scan Friday and told reporters that he now has the "green light" to begin building up toward his 2023 debut. Quintana required bone-graft surgery in March after a stress fracture in his rib cage revealed a benign tumor. He could be ready to join the rotation by the end of June if his recovery goes well.
