No. 2-ranked Naomi Osaka won her 22nd match in a row Friday, beating Ajla Tomljanovi 7-6 (3), 6-4 in the second round at the Miami Open.
Osaka shanked a serve over her opponent’s head in the final game but also hit 13 aces. She has historically made early exits in Miami, and needs only one more win for her best showing in five appearances.
Osaka hasn’t lost in more than a year, and her winning streak includes her fourth Grand Slam title at the Australian Open last month.
Daniil Medvedev, seeded No. 1 on the men’s side, needed less than an hour to beat 37-year-old Yen-hsun Lu 6-2, 6-2.
Three seeded men lost No. 8 David Goffin, No. 9 Grigor Dimitrov and No. 30 Reilly Opelka.
Goffin, a semifinalist in 2016, was upset by James Duckworth 6-3, 6-1. Dimitrov was swept by Cameron Norrie 7-5, 7-5. No. 30 Reilly Opelka lost to Alexei Popyrin 6-4, 6-2.
Other seeded women winning in straight sets included No. 6 Karolina Pliskova, No. 12 Garbie Muguruza, No. 16 Elise Mertens, No. 21 Elena Rybakina and No. 29 Jessica Pegula.
Pliskova dropped her first service game but settled down to sweep Zheng Saisai 6-2, 6-1. Muguruza, who won the Dubai Championships earlier this month, improved her 2021 record to 19-4 by beating wild card Xinyu Wang 6-4, 6-1. Mertens was a point from trailing 4-0 but rallied past Katie Boulter 6-4, 6-1.
