We're in our local playoffs that have to be finished by next Tuesday. We're down to final match that got rained out 2 weeks ago. Tonight we play and the other team only brought 6 players. No match for #3 doubles. We assume it's a default. We play for 2 hours and then rain comes. One match is finished. Other 3 are deep in the 2nd set. We reschedule for next Monday, but the other captain says #3 doubles will play then. We say no way it's a default. Anyone know what the ruling is in this kind of scenario?
