Willie Mays is certainly MLB's greatest living player as I salute him on his 90th birthday.  He is one of 11 players still living who played for the New York Giants at the Polo Grounds.  I best remember him for finishing his Hall of Fame career for the Mets from 1972-3.  He played in the 1973 World Series.
