Sixth-seeded Garbine Muguruza of Spain regrouped after having her second-round match suspended due to rain by rallying for an 0-6, 7-6 (6), 6-4 victory over American Christina McHale on Friday at the Miami Open.
Muguruza saved a match point at 6-5 in the second set tie-break and overcame a sluggish start to the third before turning her fortunes around.
"I think I had a second chance with the rain," said Muguruza, who trailed 6-0, 3-2 when the match was halted on Thursday. "It had everything, the match -- she started playing very well the first set yesterday, and I think my game was not exactly how I wanted it to be. I was missing by a little and she was not missing at all.
"I just forgot about it, and I woke up today and I said, 'Hey, this is not over.' I went to the court, I fight, and I got it in the end."
Muguruza advances to face 30th-seeded Chinese player Zhang Shuai, who also rallied from a set down to post a 4-6, 6-4, 7-5 win over Italian Sara Errani.
Third-seeded Romanian Simona Halep also needed three sets to dispatch Japan's Naomi Osaka before recording a 6-4, 2-6, 6-3 triumph.
Seventh-seeded Russian Svetlana Kuznetsova breezed to a 6-2, 6-2 victory over Luxembourg's Mandy Minella, and eighth-seeded American Madison Keys had little issue with Switzerland's Viktorija Golubic, posting a 6-1, 6-2 victory.
Romanian Patricia Maria Tig posted a 7-6 (4), 6-2 win over 22nd-seeded Frenchwoman Kristina Mladenovic, and Frenchwoman Pauline Parmentier outlasted 24th-seeded Timea Babos of Hungary, 6-7 (1), 6-2, 6-0.
American Taylor Townsend breezed to a 6-3, 6-2 win over 25th-seeded Italian Roberta Vinci, and Spaniard Lara Arruabarrena was also victorious, recording a 3-6, 6-4, 6-3 victory over 28th-seeded Romanian Irina-Camelia Begu.
