I believe it has happened numerous times, what I heard was wore like the road team had never won the first 6.
In years when the road team wins, it would be easy to get 4 road wins between both teams.
Taking it literally as written, I say yes.
This is like a Tick writing a prop in English, make sure the wording is perfect !
I know the road team won 5 times in the 96 World Series.
Braves won 1st 2 games in New York
yanks swept in Atlanta.
