Washington Nationals right-hander Josiah Gray will undergo surgery on Wednesday to repair a partial tear of his ulnar collateral ligament (UCL), ending his 2024 season and likely sidelining him for a significant part of 2025. The exact procedure, whether Tommy John surgery, an internal brace, or a hybrid, will be decided during the operation by Dr. Keith Meister in Texas. Gray's injury surfaced after a rehab assignment in late June showed a decline in velocity and performance. Gray, a 2023 All-Star, managed a 3.91 ERA last season but struggled in his two starts this year, posting a 14.04 ERA over 8⅓ innings. Despite the setback, Gray remains optimistic about his recovery and plans to stay with the team during his rehab.
