PARIS — As popular as Coco Gauff is, she knew full well that nearly all of the 15,000 fans at Court Philippe-Chatrier would be against her during the French Open semifinals Thursday. That's because Gauff, an American, was taking on a French opponent — and one who came from nowhere, 361st-ranked Loïs Boisson.
So the No. 2-seeded Gauff turned to a trick that 24-time major champion Novak Djokovic has talked about using: When the partisan crowd was loudly singing Boisson's first name, Gauff pretended they were chanting ''Coco!'' Not that it mattered much, truly, because Gauff was by far the superior player throughout a 6-1, 6-2 victory that earned her a second trip to the final at Roland-Garros.
Three years ago, Gauff missed out on a chance to leave with the trophy when Iga Swiatek beat her. This time, Swiatek won't be around for the championship match on Saturday, because her 26-match unbeaten run at the clay-court Grand Slam tournament ended earlier Thursday with a 7-6 (1), 4-6, 6-0 loss to No. 1 Aryna Sabalenka.
Sabalenka vs. Gauff will be the first No. 1 vs. No. 2 final in Paris since 2013, when Serena Williams defeated Maria Sharapova, and just the second in the last 30 years.
Sabalenka, a 27-year-old from Belarus who owns three major titles, and Gauff have split their 10 previous matchups evenly. Gauff's first Grand Slam title came via a win against Sabalenka in the 2023 U.S. Open final; Sabalenka won their most recent encounter, on a clay court at the Madrid Open a month ago.
''Anything can happen on Saturday,'' Gauff said. ''But I'm looking forward to it, and glad to be going up against a world No. 1, too.''
Gauff, a 21-year-old from Florida, figures to hear at least the occasional ''Allez, Coco!'' while meeting Sabalenka.
But that wasn't really in the offing against Boisson, who beat No. 3 Jessica Pegula and No. 6 Mirra Andreeva while becoming the first woman since 1989 to get all the way to the semifinals in her first Grand Slam tournament.
