I would still run under the assumption that team A's record is separate from team B's record. So if A wins, their record goes up, and if B loses, their record goes down.
If there's a combined record, then I have no clue how they'd determine who gets the win - generally "A" is "better" so their record would be the official one?
When in doubt, ask your coach.
And so you know, I've coached Jr. High boys v-ball, JV high school boys and girls, and assistant JV and Varsty boys and girls. My wife was the head coach. [ MFS's advice column | Ask MFS A Question ]
