Can legal sports betting juice College World Series? Matt Schmitto, RotoGrinders · June 18, 2019 at 4:46 pm The Greatest Show on Dirt began Saturday, but before that, 56 teams were eliminated between May 31st and June 10th. Odds are you have no idea what I’m referring to. The Greatest Show on Dirt is what college baseball enthusiasts call the College World Series. The NCAA trademarked the slogan in 2008, long after it became popular, then briefly benched it before its comeback in 2016. You can find the moniker plastered around TD Ameritrade Park in Omaha, Nebraska, where the final eight teams battle in a unique tournament format that lasts up to 11 days.
