Serena Williams’ first U.S. Open match since her infamous meltdown in the 2018 final will be against a familiar rival – Maria Sharapova.

Williams, the No. 8 seed, is coming off a back injury that could compromise her chances of recording a historic, record-tying 24th Grand Slam title.

Though Sharapova has slipped, it’s not an easy opener for Williams, who withdrew last week from the last big tuneup tournament in Cincinnati after forfeiting mid-match the week before in Montreal. Williams holds a 19-2 lifetime record in WTA Tour matchups against Sharapova, who is ranked No. 87, though they never have played at the US Open.

Williams, this year’s Wimbledon runner-up, has chosen not to attend the Open’s Media Day on Friday, perhaps to avoid questions about her breakdown in her loss to Naomi Osaka in last September’s final. The USTA said Carlos Ramos, the umpire in the middle of that match’s controversy, will not preside over a Serena match this fortnight.

Osaka, the defending champion, could face 15-year-old sensation Coco Gauff in the third round. Gauff received a wild card into the main draw off her stunning run to the fourth round at Wimbledon. She beat No. 2 seed Ashleigh Barty in an exhibition match Wednesday night in North Carolina. Gauff arrived Thursday in New York and was to practice on the USTA grounds later on. The Open draw was announced during a ceremony on the grounds.

In the men’s draw, Novak Djokovic, the defending champion and No. 1 seed, had the misfortune of getting Roger Federer on his half of the draw, meaning they could meet in the semifinals. They staged an epic five-set marathon in the Wimbledon final, which Djokovic won for his 16th Grand Slam title.

Rafael Nadal is the only member of the Big 3 in his half of the draw. Nadal and Federer have never met at the Open, and would have to do so in the final this year. In the first round Nadal will get John Millman, who stunned Federer in the fourth round of the Open last year.
