Southern Indiana Wiffle Ball tournament offers $350 prize at Boonville American Legion

Southern Indiana’s one-day Wiffle Ball tournament at Boonville American Legion lined up a simple sell: show up at 8 a.m., bring five players, survive pool play and leave with $350. The July 18, 2026 event capped the field at 25 teams, a number that keeps the day tight and the race for a spot fast-moving before the first ball is even thrown.

That setup is what gives the tournament its edge. A five-player roster in Wiffle Ball leaves little room to hide, especially in a format where the winning prize is tied to pool play. Every inning in the opening stage carries weight, because one bad outing can put a team behind in a field built for quick elimination and a single-day finish. At Boonville, the prize is not enough to turn the event into a major-money circuit stop, but it is enough to make teams treat it like a real test instead of a casual summer gathering.

The compact roster size also changes how teams have to build. With only five players available, the difference between a team with one dominant thrower and one with usable depth becomes sharper. In a one-day tournament, that matters even more because fatigue can creep in fast and there is no second weekend to reset. The Boonville format rewards clean defense, reliable pitching and hitters who can do damage without needing a long lineup to carry them.

The Boonville event fits neatly alongside bigger Indiana Wiffle Ball dates on the calendar. The World Wiffle Ball Championship is scheduled for Aug. 15-16, 2026, at the Crown Point Sportsplex in Crown Point, with four round-robin games on Saturday and Sunday single-elimination play for teams that go 2-2 or better. That tournament calls itself the 47th championship and says the event began in 1980, which gives the state a long-running competitive standard.

Indiana State Wiffleball Championship listings point in the same direction. That event is advertised for the first Saturday in August every year, with adult teams ages 14 and up entering for $100 and youth teams age 13 and under entering for $80. One listing also says the entry fee helps three kids who could not otherwise afford to play a sport sign up and participate, and registration is available by phone at 317-888-0070. Against that backdrop, Boonville looks like the smaller, sharper version of the same idea: a fast, local tournament with enough cash on the line to make every pool-play inning feel expensive.
