Chicago White Sox right-hander Mike Vasil is set for season-ending Tommy John surgery after leaving his most recent spring training start with right elbow soreness. The team says Vasil’s surgery will be performed in the coming weeks by Texas Rangers team physician Dr. Keith Meister. Vasil exited a start against the Los Angeles Dodgers in the fourth inning Saturday. He was 5-3 with a 2.50 ERA as a rookie last year, when he made three starts in 47 appearances.
