The Alexandria Aces won the 2009 Continental Baseball League championship series (in Alexandria, Louisiana) – defeating the Big Bend Cowboys in two straight games of the best-of-3 series. The final score of Game 2 was 7-3 in favor of the Aces. The Cowboys replaced the Bay Area Toros who won the 1st round of the playoffs (over the Cowboys) but elected not to go to Alexandria for the championship series.
