26-year-old Washington Nationals pitcher Josiah Gray will undergo season-ending surgery for a torn ulnar collateral ligament (UCL) in his elbow. The exact procedure, whether an internal brace or Tommy John surgery, will be determined during the surgery. Gray, who was the opening day starter, will not participate for the remainder of the season after this planned operation next week.
