Jackie Robinson would be proud . Chicago 's Little League team named for the baseball icon -- who broke his sport 's color line -- is headed to the Little League World Series championship , after topping Las Vegas in the U.S. title game on Saturday . The Jackie Robinson West squad -- which is composed entirely of young African-Americans -- will square off with the tournament 's international champions from Seoul , South Korea , in Sunday 's final . The South Koreans advanced after crushing Japan 12-3 earlier Saturday . Chicago entered its own contest Saturday as the underdog . Its foe , Las Vegas , had beaten every team it faced -- including Chicago , which it crushed by a 13-2 score . But this time proved to be very different . The two squads were tied 3-3 after the first inning , before the Jackie Robinson West entry jumped ahead by one run the next inning . Las Vegas took the lead in the fifth on a two-run home run by Brad Stone , only to have Chicago answer with three runs of its own . Ed Howard moved from his usual perch at shortstop to pitcher in the sixth and final inning and -- with a game-ending double play -- sealed Chicago 's 7-5 win . That victory set off jubilant celebrations at the game in Williamsport , Pennsylvania , as well as Chicago , including among locals who cheered after watching the final outs at a Cubs game at Wrigley Field . Chicago Mayor Rahm Emanuel credited `` their positive attitude and success on the field ( for rallying ) people from every neighborhood . '' The boys from Chicago 's South Side also got hearty congratulations from outside the Windy City , including ex-Chicago White Sox great and baseball Hall of Famer Frank Thomas and longtime President Barack Obama adviser David Axelrod . `` Congrats to the Chicago Little Leaguers on winning the US title ! , '' tweeted Steve Kerr , a former standout with the NBA 's Chicago Bulls and now coach of the Golden State Warriors . `` So inspiring to see the poise and skill at such young ages . Awesome . ''
