ORWBL World Series
The finale of the summer, the ORWBL World Series is a best of seven series for the Old Republic Wiffle®Ball League Championship. The first ORWBL World Series was held in 2008, after the 2007 ORWBL World Series was cancelled due to a work stoppage.
The Granger Panthers swept the Maple City Magic (4-0) to win the 2021 World Series. Griffin Smith was named the World Series' Most Valuable Player following his walk-off homerun in the series-clinching game four. This was Granger's first ORWBL championship.
