Top seeds Zverev, Sabalenka advance in Miami Open

MIAMI — World No 1 Aryna Sabalenka reached the last 16 at the Miami Open when Elena-Gabriela Ruse retired injured on Saturday, while men's top seed Alexander Zverev beat Jacob Fearnley 6-2, 6-4 to reach the third round.

Sabalenka, who arrived in Miami fresh off a defeat in last week's Indian Wells final, wrapped up the first set 6-1, before Romanian Ruse was forced to retire with a right thigh injury.

Up next for the Belarusian three-time Grand Slam champion will be defending Miami champion American Danielle Collins, who beat Swiss qualifier Rebeka Masarova 6-4, 3-6, 6-3.
