The problem with a play-till-you-win match, is if it isn’t a final, it could ruin the final. Just look at Wimbledon… after that marathon Mahut-Isner match, Isner could barely play the next match. Now I hope I’m proven wrong, but there is every likelihood that this recent marathon Anderson-Isner semifinal is just as likely to have ruined the final.
Surely they could set things up so that is a full day’s rest between the semifinal and final.
One day’s rest is insufficient recovery time after an 11-hour match. (that was the length of the Mahut-Isner match)
What are the odds a soccer game would go for 11 hours?
I’d guess about the same odds as for a tennis match.
Having said that, I’ve always thought there should be better ways than penalty kicks. What about reducing the number players on each team by 1 (or 2), at each 10 minutes of overtime play?
