Sanchez underwent season-ending right shoulder surgery in Los Angeles on Tuesday, David Wilson of the Miami Herald reports.
Dr. Neal ElAttrache supervised the procedure, which repaired a capsule tear and cleaned out the backside of Sanchez's shoulder joint. Marlins general manager Kim Ng said that Sanchez doesn't have a timeline to resume throwing or performing workouts with his right arm, but the organization is hopeful that the prized 22-year-old will be ready to go for Opening Day in 2022. Sanchez looked like a potential frontline starter when he received his first taste of the big leagues in 2020, producing a 3.46 ERA and 33:11 K:BB in 39 innings over his seven starts with Miami.
