GarbineMuguruza - Cropped

Garbine Muguruza had an easy win over Nico Gibbs in the third round of the Miami Open on Sunday.

Garbine Muguruza breezed into the fourth round of the Miami Open to set up a clash with Victoria Azarenka for a place in the quarterfinals. 

Muguruza defeated Nicole Gibbs in straight-sets, while two-time champion Azarenka was just as dominant against Magda Linette, winning 6-3 6-0. World No. 3 and second seed Angelique Kerber had a much more difficult task against Kiki Bertens, battling from a set down before her Dutch opponent retired in the third. 

Easy day for the seeds

Only one seed departed on Sunday, with ninth seed Roberta Vinci eliminated by Madison Keys 6-4 6-4.  Kerber, Azarenka and Muguruza were all joined in the next round by 24th seed Johanna Konta and 32nd seed Monica Niculescu. Konta came from behind to beat Elena Vesnina 4-6 6-1 7-6 (7-3), while Niculescu eased past Coco Vandeweghe 6-4 6-1. 

Muguruza dominant

The Spaniard dropped just two games on her way to a dominate victory over her American opponent.  Gibbs, ranked 95th in the world, had won in straight-sets on her way to the third round but Muguruza proved too high of a mountain to climb. 

The match lasted just 56 minutes as fourth seed Muguruza won 6-1 6-0 to set up a fourth-round clash with Azarenka.

Kerber on the ropes

Kerber found herself a set down but recovered well before Bertens was forced to retire, with the score 1-6 6-2 3-0. "I think Kiki's a great player," the German said in her on-court interview. "She played very well in the first set and I was not finding my rhythm at the beginning.

"But I was trying to stay in the match, trying to fight and play my game. At the end, of course, it's always sad when the opponent retires; I hope she gets very well very soon, but I'm happy to be in the next round."

Monday schedule

All top five seeds feature on Monday, with eight-time champion Serena Williams, Kerber, Agnieszka Radwanska, Muguruza and Simona Halep up against Svetlana Kuznetsova, Timea Babos, Timea Bacsinszky, Azarenka and Heather Watson respectively.
