The San Francisco Giants and the Kansas City Royals -- who are battling for this year's World Series title -- have rosters featuring whites, blacks, Latinos and Asians. Just down the highway from where the Major League Baseball champion will be crowned this week, the Negro Leagues Baseball Museum tells a different story -- one of segregation and struggle. While some black players -- like Jackie Robinson, who broke the color barrier in 1947 with the then-Brooklyn Dodgers -- rose to the sport's highest heights, others never made it to the big leagues. Frustrated by the unofficial ban, black players moved to form their own leagues.
