“I just don’t know,” Sharapova, 32, said. “I haven’t thought of my schedule moving forward from here yet.”
Joining Sharapova in a first-round exit were Johanna Konta, a three-time major semifinalist; Amanda Anisimova, a 2019 French Open semifinalist; and Felix Auger-Aliassime, the 20th-seeded man.
Seeded winners included the two-time major champion Simona Halep and No. 1 Rafael Nadal, who began his bid to equal Roger Federer’s record of 20 Grand Slam singles titles with a 6-2, 6-3, 6-0 victory over Hugo Dellien.
The man Nadal beat in last year’s United States Open final, No. 4 Daniil Medvedev, eliminated the 2019 Australian Open quarterfinalist Frances Tiafoe of the United States in four sets. Also advancing: the three-time major champion Stan Wawrinka; the two-time French Open runner-up Dominic Thiem; No. 12 Fabio Fognini; No. 16 Karen Khachanov; and No. 23 Nick Kyrgios, the Australian who spurred players to contribute funds to relief efforts for the country’s wildfire crisis. The TV analyst John McEnroe was even inspired to pony up $1,000 per set that Kyrgios wins the rest of the way in the tournament.
In early second-round play Wednesday, Naomi Osaka, the reigning champion and the No. 3 seed, beat 42nd-ranked Zheng Saisai, 6-2, 6-4, in swirling winds at Margaret Court Arena. Caroline Wozniacki, the former No. 1 who has announced she will retire after this tournament, survived against the No. 23 seed, Dayana Yastremska, 7-5, 7-5, and top-seeded Ashleigh Barty dispatched Polona Hercog, 6-1, 6-4. Coco Gauff, the 15-year-old American phenom, defeated Sorana Cîrstea, 4-6, 6-3, 7-5, and will face Osaka in the third round.
