Daniil Medvedev celebrated his rise to second in the world with a seamless entry into the Miami Open on Friday, trouncing Taiwan's Lu Yen-Hsun in less than an hour. Russia's Medvedev needed just 56 minutes to subdue Lu 6-2, 6-2, firing nine aces with just one double fault as he advanced to a third-round meeting with Australian Alexei Popyrin, a 6-4, 6-2, winner over 30th-seeded American Reilly Opelka. Women's world number two Naomi Osaka, seeded second behind top-ranked Australian Ashleigh Barty, had a tougher time, but conquered her nerves in her first match since winning the Australian Open to beat Aussie Ajla Tomljanovic 7-6 (7/3), 6-4. Men's third seed Alexander Zverev, ranked seventh in the world, became the biggest upset victim so far in the prestigious ATP Masters and WTA hardcourt tournament, falling 1-6, 6-3, 6-1 to 83rd-ranked Finn Emil Ruusuvuori. Medvedev, the top seed in an ATP Masters event for the first time, was all over Lu from the opening game.
