Winning the pennant means everything in sports because if your team wins it then your team is going to the championship and in baseball if your team wins the pennant then they're going to the World Series. The video above shows teams from the National and American Leagues' winning the pennant and going to the World Series. It starts from 2000 and ends in 2015, this year I hope that the Cubs win the National League pennant and go to the World Series and win.🙂
