Despite finishing only three games behind the Cleveland Indians in the 1948 pennant race, Harris was relieved of his duties and replaced by Casey Stengel, who had a reputation of being a clown and managing bad teams. His tenure as Yankees' field manager, however, was marked with success. The "underdog" Yankees came from behind to catch and surprise a powerful Red Sox team on the last two days of the 1949 season, a face-off that fueled the beginning of the modern Yankees–Red Sox rivalry. By this time, however, DiMaggio's career was winding down, and the "Yankee Clipper" retired after the 1951 season. This year marked the arrival of the "Oklahoma Kid", Mickey Mantle, who was one of several new stars to fill the gap.
