But Andreescu’s victory was also a flashback, in some ways, to last year when Naomi Osaka, a 20-year-old playing in her first major final, defeated Williams to win at the U.S. Open.
Like Osaka in 2018, Andreescu won the first title of her career in Indian Wells, and then went on to win her first Grand Slam title at the U.S. Open against Williams.
After shaking Williams’s hand, Andreescu put both hands to her head and then dropped to the blue court and lay on her back, arms and legs wide with the last ball used in the match resting nearby. After rising, she quickly climbed into the stands to celebrate with her team, including her coach, Sylvain Bruneau, and her parents.
“I believe in you; I believe in you,” Bruneau said as they embraced.
Andreescu, seeded No. 15 at Flushing Meadows, will break into the top 10 in the rankings at No. 5 on Monday, and Patrick Mouratoglou, Williams’s longtime coach, believes she is headed higher.
“I think she’s going to be No. 1 soon,” Mouratoglou said before the final. “Not too soon, but in the future, because she has everything that’s needed.”
It is easy to understand the enthusiasm. Andreescu has power and speed but also a precociously complete game with a pronounced and unusual taste for changing paces, spins and trajectories during rallies. She is comfortable blasting from the backcourt, defending with slice in the corners or attacking the net and knocking off points with volleys or her fine overhead.
She also has a good serve and, to complete the new-age package, a taste for competition.
“She’s a warrior, and she’s a street fighter,” Bruneau said.
