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 No 2 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. He belted 24 winners to become the second player – along with compatriot Andrey Rublev – to reach 15 match wins this year.
