Probably the most sensational figure in baseball last year, was Rookie Charley Keller, of the World Champion Yankees. Up from Newark, Keller was placed in the regular right field post shortly before mid-season, and was never ousted. He hit .334 during the regular season, driving across 83 runs with 133 hits, but reached his peak in the World Series by wrecking the Reds almost single-handed. He topped everybody with seven hits, including three damaging homers, a triple and a double, averaged .438, scored eight of the Yankees' 20 runs, and played a flawless game afield. Keller is a graduate of the University of Maryland and is regarded by baseball experts as a "natural."
