PARIS — At the past six Grand Slams, there have been six different women’s champions.That’s not abnormal on the WTA Tour. It also happened between 2019 and 2020, and between the end of 2016 and the start of 2018.The difference between now and then is that four of those six major winners are established stars in the women’s tennis firmament. Aryna Sabalenka, Iga Świątek, Elena Rybakina and Coco Gauff are all multiple Grand Slam champions, and Sabalenka and Świątek have spent long periods as world No. 1.But since January 2025, no one has doubled up. Instead, they have been joined on the winner’s podium by Madison Keys, at that year’s Australian Open, and by Mirra Andreeva, who won her first Grand Slam singles title at the French Open Saturday.Some of the names in the older sequences, like Jeļena Ostapenko (2017 French Open) and Sloane Stephens (2017 U.S. Open), were unseeded surprise packages. Keys, by contrast, had long been hailed as a future major champion, even though she has not been a factor late at majors since. Andreeva, 19, is ready to stay among the elite.“I’m already thinking of how I’m going to prepare for the grass season,” Andreeva said in a news conference after her 6-3, 6-2 win over Polish qualifier Maja Chwalińska. “I feel like this thing is a little bit addicting, and I really want to do my best to experience all of this for the second time.”Her coach, Conchita Martínez, added in a news conference afterward that “the sky is the limit” for Andreeva.“It’s for her to improve and to get better. Then bigger things are coming.”That would leave five established stars at the top of the sport, all vying to exert some sort of dominance at the majors that has proven elusive as of late. Throw in the other three players in the world’s top eight as of Monday’s rankings — Jessica Pegula and Amanda Anisimova of the U.S., and Ukraine’s Elina Svitolina — and the suite of genuine contenders gets larger.
