Thanasi Kokkinakis has made a winning start to his Miami Open campaign, scoring a straight-sets win against No.20 seed Frederico Ferreira Silva in the opening qualifying round.
The 24-year-old Kokkinakis fired nine aces in the 104-minute victory. He lost only three points on serve in a dominant opening set, before withstanding a challenge from the world No.174 from Portugal in the second set.
Kokkinakis' victory sets up a final qualifying round showdown with world No.196 Mario Vilella Martinez of Spain, who upset No.4-seeded German Cedrik-Marcel Stebe today.
World No.243 Kokkinakis has great memories in Miami, an ATP 1000 tournament where he defeated world No.1 Roger Federer as a qualifier in 2018.
Australia's Arina Rodionova and Astra Sharma both lost their opening women's singles qualifying matches.
