13 is possibly the most daring of the various jersey numbers. It necessitates that the wearer set aside superstition and laugh in the face of Lady Luck. The disadvantage of No. 13 is that fewer men have worn it, making a search for the "best ever" in any specific sport harder. The first recorded use of the number was by Willie Mays on April 17, 1955. He wore #13 for the San Francisco Giants during their inaugural season in the National League. Before that time, the number had been unassigned for several years. However, it is believed that many players used to wear numbers in the high 20's or low 30's when they were with other teams before being released by those teams and signing with the Giants in 1955. In addition to Mays, only three other players have won the MVP award while wearing #13: Joe DiMaggio in 1936, Carl Yastrzemski in 1967, and Mike Schmidt in 1980. DiMaggio and Schmidt both played their entire careers with the San Francisco Giants. Joe D's son Vince also wore #13 when he played in Major League Baseball from 1969-1979. He spent his final season with the Philadelphia Phillies. A total of 14 men have won the Triple Crown while wearing #13 including two-time winner Joe DiMaggio and 1947 champion Bill Dobson of the New York Yankees.
