Sabalenka, Osaka & Gauff reach last 16 in Miami

Aryna Sabalenka was beaten in three sets by Mirra Andreeva in the Indian Wells final last weekend.

World number one Aryna Sabalenka moved into the Miami Open last 16 after opponent Elena-Gabriela Ruse retired injured, while there were wins for Naomi Osaka and Coco Gauff.

Sabalenka had taken the first set 6-1 before Romanian Ruse retired with a thigh problem in the first game of the second.

Japans Osaka survived a scare to eventually overcome American wild card Hailey Baptiste in a match lasting nearly three hours.

World number 98 Baptiste was a break up and serving at 4-3 in the decisive third set, but Osaka came back well.

The four-time Grand Slam champion held serve before breaking Baptiste again to take the match 7-6 (8-6) 3-6 6-4 in two hours, 59 minutes and 57 seconds - the longest womens match of the tournament so far.

There were no such problems for third seed Gauff, who continued her fine tournament with a comfortable straight-set win over Greeces Maria Sakkari.

The 21-year-old world number three, who needed just 47 minutes to beat Sofia Kenin 6-0 6-0 in the previous round, won 6-2 6-4 to reach the last 16 in Miami for the third time in her career.

Italian sixth seed Jasmine Paolini also went through after Tunisian opponent Ons Jabeur retired injured when trailing 4-3 in the first set.
