<human>: Mickey Charles Mantle (October 20, 1931 - August 13, 1995), nicknamed The Commerce Comet and The Mick, was an American professional baseball player. Mantle played his entire Major League Baseball (MLB) career with the New York Yankees as a center fielder and first baseman, from 1951 through 1968. Mantle was one of the best players and sluggers, and is regarded by many as the greatest switch hitter in baseball history. Mantle was inducted into the National Baseball Hall of Fame in 1974 and was elected to the Major League Baseball All-Century Team in 1999.

Mantle was invited to the Yankees instructional camp before the 1951 season. After an impressive spring training, Yankees manager Casey Stengel decided to promote Mantle to the majors as a right fielder instead of sending him to the minors. Mickey Mantle's salary for the 1951 season was $7,500.  Mantle was assigned uniform #6, signifying the expectation that he would become the next Yankees star, following Babe Ruth (#3), Lou Gehrig (#4) and Joe DiMaggio (#5). Stengel, speaking to SPORT, stated "He's got more natural power from both sides than anybody I ever saw." Bill Dickey called Mantle "the greatest prospect [he's] seen in [his] time."  After a brief slump, Mantle was sent down to the Yankees' top farm team, the Kansas City Blues. However, he was not able to find the power he once had in the lower minors. Out of frustration, he called his father one day and told him, "I don't think I can play baseball anymore." Mutt drove up to Kansas City that day. When he arrived, he started packing his son's clothes and, according to Mantle's memory, said "I thought I raised a man. I see I raised a coward instead. You can come back to Oklahoma and work the mines with me." Mantle immediately broke out of his slump, going on to hit .361 with 11 homers and 50 RBIs during his stay in Kansas City.  Mantle was called up to the Yankees after 40 games with Kansas City, this time wearing uniform #7. He hit .267 with 13 home runs and 65 RBI in 96 games. In the second game of the 1951 World Series, New York Giants rookie Willie Mays hit a fly ball to right-center field. Mantle, playing right field, raced for the ball together with center fielder Joe DiMaggio, who called for the ball (and made the catch). In getting out of DiMaggio's way, Mantle tripped over an exposed drain pipe and severely injured his right knee. This was the first of numerous injuries that plagued his 18-year career with the Yankees. He played the rest of his career with a torn ACL. CANNOTANSWER
