Little League Baseball has stripped the U.S. championship from the Chicago-based Jackie Robinson West team and has suspended the coach for violating a rule prohibiting the use of players who live outside the geographic area that the team represents, it was announced Wednesday. The Jackie Robinson West team, the first all-African-American team to win the championship, must vacate wins from the 2014 Little League Baseball International Tournament — including its Great Lakes Regional and United States championships.

The team's manager, Darold Butler, has been suspended from Little League activity, and Illinois District 4 Administrator Michael Kelly has been removed from his position. The organization found that the Jackie Robinson team used a falsified boundary map, and that team officials met with neighboring Little League districts in Illinois to claim players and build what amounts to a superteam.
