Back in March, after losing to Bianca Andreescu in the third round of the Miami Open, and only a few days after losing to her in the final of Indian Wells, Angelique Kerber approached the net for the traditional post-match handshake with a grim look and a message. “You’re the biggest drama queen ever,” she said to the Canadian, who was then eighteen, pointedly looking away as they shook hands. Kerber, who is known as one of the nicer players on tour, was irritated by a medical time-out that Andreescu had taken after the first set, to deal with an injured shoulder; no doubt Kerber was also angry about losing to her twice in one week. Before 2019, Andreescu was mostly unknown. She began the year ranked No. 152 in the world. But, ever since, she has defeated some of the best players in the world, demonstrating a stunning array of skills—flat, deep ground strokes topping out at close to ninety miles per hour; moony topspin shots designed to disrupt the rhythm of her opponent; nasty skidding slices and delicate drop shots—and the intelligence, imagination, and audacity to use them effectively. She exposed Kerber’s defense-minded game, which Kerber has used to win three grand slams, as one-dimensional. More than that, though, she showed self-assurance—the kind of competitive intensity and unapologetic swagger usually reserved for a few legends of the game. She carried herself more like Serena Williams than like what she was: a teen-ager with a wild card.

That shoulder problem turned out to be a torn rotator cuff. Andreescu had to retire from her fourth-round match in Miami. After pulling out of her second-round match at the French Open, still struggling with the injury, she missed the entire grass season. Then she returned to tour—and promptly won the Canadian Open. She has not lost a completed match since March 1st. She has never, in her career, lost to a top-ten player. (She is now 8–0.) And, on Saturday, she defeated Williams in dramatic fashion, 6–3, 7–5, to win the U.S. Open.

That was part of the story of the women’s final. There was also the player on the other side of the net. Williams came into the match just having won her hundred and first match at the U.S. Open. She was seeking her twenty-fourth grand-slam title, which would tie her with Margaret Court’s total—a record that, given the number of titles Court won in Australia, against weaker fields, only means anything because it seems to have become a strange sort of stumbling block for Williams. Since coming back last year, after giving birth, she has made four slam finals. The over-all level of the tour had risen in her absence, and yet no one else could claim that kind of consistency. But the finals matches themselves have been another story. She had yet to win a single set in any of those matches.

This time, though, there was an air of inevitability about her. She had played well all tournament, starting with a sharp performance against her favorite honing steel, Maria Sharapova, and including an utter dismantling of Wang Qiang, in forty-four minutes, in the quarter-finals, and an even more impressive win against Elina Svitolina, in the semifinals. It wasn’t solely the show of her usual power, which few players can match. She was also fit in a way that she hadn’t been since recovering from the difficult birth of her daughter, which was followed by a string of injuries. Her movement—not only forward and back but side to side—was finally there, both steady and explosive. Against Svitolina, who has risen into the top five on the strength of her ability to extend points, Williams was actually the superior mover, and won the majority of their long rallies. She had, too, a calmness about her that had often seemed lacking during her comeback. As a cultural icon—as an inspirational figure, as a brand—Williams has never been bigger, but during the finals matches her aura had seemed diminished. She has won countless matches in her career by imposing herself before the first serve was even struck, but her past four finals opponents had come out obviously feeling less pressure than her. This was understandable, given what she was up against—not only her opponent but also the expectations, even the assumptions, of millions, most of all herself. But, during this tournament, the confidence seemed back. Her first serve, always the most important weapon, was humming at high speeds; the tuning fork seemed to be struck.

It wasn’t that Andreescu was oblivious to any of this; she knows the legend of Williams as well as anyone. There was never a time, in fact, during Andreescu’s life when Williams wasn’t winning; Williams won her first U.S. Open title before Andreescu was even born. Andreescu admitted to being nervous before the match. But she seemed more concerned with her own inevitability. She really did carry herself like a queen.

Williams began the match with an ace, but Andreescu was unfazed. She put pressure on Williams’s serve with heavy, attacking returns. “I think she was intimidated a little bit by it,” she said afterward—not something I can remember anyone saying about Williams, ever. But perhaps she was right: Williams double-faulted twice to give Andreescu the first break. From there, Andreescu seemed only to get stronger. She used big body serves to bail her out of trouble—much the way Williams always has. She used the depth of her ground strokes to set up sharp angles or rockets down the line. She set patterns and broke them, and seemed to unsettle Williams, who put only forty-four per cent of her first serves into play and finished with eight double faults. Williams’s footwork was off. Andreescu’s shouts of “Let’s go!” and “Come on!” echoed strangely in the silent stadium. She reached her first championship point up 5–1 in the second set. It seemed, for a moment, hard to watch.

But Williams, ever the competitor, fought back. She saved championship point with a forehand into the corner, and then started to move. Andreescu was the one then whose racquet looked heavy, her swings slower and her serves starting to miss. Williams levelled the score at 5–5, lifted by and in turn lifting a raucous crowd—which was so loud, and so much in Williams’s favor, that at one point Andreescu covered her ears to try to block it out.

Another young player might have cracked at that point, watching such a lead slip away, playing passively, while knowing what Williams can do when she finds her form. Andreescu, though, settled herself, held serve, and broke to win the match.

There was an amusing moment after the match, when Andreescu’s coach, Sylvain Bruneau, was told that he was holding the trophy backward. “I’m not used to this,” he said. “Holding trophies.” “Well, get used to it,” Andreescu said. She was joking—but, also, not at all. Not long ago, that might have been heard as arrogance, especially coming from a young woman. But that is changing. The unapologetic attitude of the U.S. women’s national soccer team is part of that, and the self-possession of Simone Biles as she performs such daring feats is, too. More than anyone, Williams, along with her sister, modelled that kind of self-belief. Given all the people who were, back then, set against them, they probably didn’t have a choice. It is a measure of how much Williams has accomplished that the young woman who beat her on Saturday, nearly half her age, has inherited the world that Williams made.
