Cam Schlittler has become an instant star for the New York Yankees, delivering a dominant performance against the rival Boston Red Sox in a playoff elimination game. The 24-year-old rookie pitched eight overpowering innings with 12 strikeouts and no walks as New York beat Boston 4-0, advancing to the Division Series against Toronto. Schlittler, who grew up a Red Sox fan in Massachusetts, prepared by speaking with Yankees great Andy Pettitte. Schlittler’s fastball reached 100 mph, and the right-hander struck out more batters than any other Yankees pitcher in a postseason debut. New York manager Aaron Boone praised Schlittler’s fearless approach.
