we got some more players for him or not". Repeating success (1950–1953) During the 1949 season, Stengel had been more subdued than he usually was, but being the manager of the defending world champions and the Major League Manager of the Year relieved his inhibitions, and he was thereafter his talkative self. He also was more forceful in running the team, not always to the liking of veteran players such as DiMaggio and Phil Rizzuto. As part of his incessant shuffling of the lineup, Stengel had DiMaggio play first base, a position to which he was unaccustomed and refused to play after the first game. Stengel considered DiMaggio's decline in play as he neared the end of his stellar career more important than his resentment. In August, with the slugger in the middle of a batting slump, Stengel benched him, stating he needed a rest. DiMaggio returned after six games, and hit .370 for the rest of the season, winning the slugging percentage title. Other young players on the 1950 team were Billy Martin and Whitey Ford. The ascendence of these rookies meant more of the Yankees accepted Stengel's techniques, and diminished the number of those from the McCarthy era who resented their new manager. The Detroit Tigers were the Yankees' main competition, leading for much of the summer, but the Yankees passed them in the middle of September to win the pennant by three games. In the 1950 World Series, the Yankees played the Phillies, another of Stengel's old teams. The Yankees won in four games. Before spring training in 1950, the Yankees had pioneered the idea of an instructional school for rookies and other young players. This was the brainchild of Stengel and Weiss. Complaints from other teams that the Yankees were violating time limits on spring training and were using their money for competitive advantage led to modifications, but the concept survived and was eventually broadly adopted. Among those invited to the 1951 early camp was 19-year-old Mickey Mantle, whose speed and talent awed Stengel, and who had spent the previous year in the minor leagues. Stengel moved Mantle from shortstop to the outfield, reasoning that Rizzuto, the shortstop, was likely to play several more years. Both Mantle and the Yankees started the 1951 season slowly, and on July 14, Mantle was sent to Kansas City to regain his confidence at the plate. He was soon recalled
