Yep.
Not sure if you saw this article I linked on previous page.
Why Women Don’t Play Best-Of-Five Matches At Grand Slams – ThinkProgress
Again the title is misleading as one cannot discern why. The article as well goes into how often through history that Women have played 5 sets in slams, and women are more conditioned physically now than ever, with all of todays modern training at their disposal and diet, support etc.
Its interesting that we're posting here as hockey fans and you shouldn't have to state the bolded. 7 game playoff series exist because they are considered more determinative than say 5 game series or best of 3 game series.
Obviously 5 sets tell more than 3 sets. I mean there could be some proviso. Say if the first sets are knockouts, like 6-0, 6-0 there is no point playing a third, kind of a mercy rule. But almost anybody in Tennis is saying that in womens play there should be 5 sets in Slams at least in quarterfinals on.
So I don't really know why the arguments against it. Women can play 5 sets, and have, and should. Only the viewers, sponsors, networks are being denied more tennis. It seems incredibly silly at this time of pandemic and huge potential viewing audiences not to play 5 sets.
ps Bobby Riggs was age 55 in the "historic" match with Billy Jean King, who was an active WTA player, in prime, age 28. Riggs had been retired from Tennis for 20yrs. Only stated because the article posits a pretty silly view on the match.
