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.

​

In 2025 we saw the Elkhart BFAM franchise win their first ORWBL World Series title after sweeping the Granger Panthers (4-0) to complete one of the most dominant seasons in ORWBL history.  Elkhart finished the regular season with a 29-1 record before rolling through the Postseason en route to a World Series title.  BFAM's Nick Fritz took home World Series MVP honors as it was truly a storybook season for the entire Elkhart franchise.
