James Robert Lemon (March 23, 1928 – May 14, 2006) was an American right and left fielder, manager and coach in Major League Baseball. A powerful, right-handed hitting and throwing outfielder, Lemon teamed with first baseman Roy Sievers and later with slugger Harmon Killebrew and outfielder Bob Allison to form the most formidable home run-hitting tandem in the 60-year history of the first Washington Senators franchise.
