Seattle Wiffleball sets July 19 in-season tournament at Cowen Park

Seattle Wiffleball put its 2026 In-Season Tournament on the calendar for Sunday, July 19 at Cowen Park, and the setup gave the league a fast, compact test of which clubs could handle pressure from the first pitch. Six teams were set to play, with morning mini-games determining seeding before the field shifted into a double-elimination bracket in the afternoon.

The format made the event more than a one-off showcase. Seattle Wiffleball said the trophy was to be awarded by 4 PM, which meant the entire day had to run on tight timing and sharp game management. A league social post spelled out the opening window even more clearly: 10 mini-games at 10 a.m. to earn a seed. Another post said the double-elimination bracket would run from noon to 4 p.m., leaving little room for a slow start or a long reset after an early loss.

That structure put real weight on the seeding phase. In a six-team field, every mini-game could shape the bracket path, and the difference between a favorable first-round matchup and a difficult one could decide who survived into the late afternoon. The double-elimination format still offered a second life, but it also demanded depth, stamina and quick adjustments once the bracket started compressing the field.

The tournament also fit squarely into the league’s summer rhythm. Seattle Wiffleball says it was established in 2015 and describes itself as the “Original Wiffleball League of the Pacific Northwest,” language that frames the event as one of its marquee dates rather than a side attraction. The league plays Sundays at Cowen Park from May to August, and its 2026 regular-season schedule had already listed games for Sunday, May 3, Sunday, May 10 and Sunday, May 17 before the July tournament date arrived.

That broader calendar gives the In-Season Tournament a clear place in the season: a midyear checkpoint where the standings, the bracket draw and the pressure of a one-day format all collided. Seattle Wiffleball also used a registration link to promote the event, reinforcing that the tournament was both a competitive cutoff point and a central organizing date for the league’s summer slate.
