19. Ted Williams
Teams: Red Sox
Williams' career counting stats are excellent: 521 home runs, 2654 hits—that's a Hall of Fame material right there. But Williams lost nearly 5 years of his career serving as a Marine fighter pilot in WWII and Korea (he flew 39 combat missions in Korea). And after he retired, he used his Hall of Fame induction speech to lobby for the inclusion of Negro League players at Cooperstown. Defending your country and calling its national pastime to task for its racist history? Badass.
