Stefanos Tsitsipas and Alexander Zverev both have been one of the best players for the past several years but neither has won a Grand Slam. Zverev missed out on a great chance to win his first Grand Slam two years ago, when he blew a two-set lead against Dominic Thiem in the US Open final.
A year ago, Tsitsipas was on the verge of winning his first Grand Slam but world No. 1 Novak Djokovic recovered from two sets down to beat the Greek in the French Open final. "Alexander Zverev, who reached the final at the 2020 US Open, he could have won the US Open if it was best-of-three.
You have my case as well at Roland Garros [last year]. You have many other cases," Tsitsipas said, per Sportskeeda. I'm pretty sure you can find a lot of cases where the loser of a Grand Slam final won the first two sets and still somehow found themselves losing in the end.
The winners of Grand Slams would be very different if the format was best-of-three in men."
Tsitsipas OK with the current format used at the Grand Slams
Even though Tsitsipas suggested that the best-of-five-sets format cost him a victory at last year's French Open, he has no problem with the current format used at the Majors.
"[Best-of-five] is a different psychology. I'm sure it allows the greater players, the ones that have more experience when it comes to winning Grand Slam titles, to fight back. It gives them more chances to get back into the match.
I like it anyways," Tsitsipas added. "I think it gets very physical. It makes for a great show as well. It would be the traditional thing. I don't think there's anything wrong with it. Maybe women can also play best-of-five [in Grand Slams], I guess." Tsitsipas reached the semifinal at this year's Australian Open, before losing to Daniil Medvedev.
