Major League Baseball and its participating clubs have retired various uniform numbers over the course of time, ensuring that those numbers are never worn again and thus will always be associated with particular players or managers of note. The use of numbers on uniforms to better identify one player from another, and hence to boost sales of scorecards, was tried briefly by the Cleveland Indians of 1916. The first team to permanently adopt the practice was the New York Yankees of 1929. By 1932, all sixteen major league clubs were issuing numbers, and by 1937, the leagues passed rules requiring it (wikipedia).
In order to solve this puzzle, you'll have to figure out which number each of the players wore and then plug that into the coordinates.
N (Jackie Robinson) (Dizzy Dean) . (Ted Williams)(Roberto Clemente)
W (Billy Martin)(Jim Palmer) (Jimmie Reese) . (Barry Larkin)(Mickey Mantle)
