Coco Gauff and Iga Swiatek book their place in Miami Open fourth round

Gauff trailed 4-2 in the first set and had to save two break points to avoid falling further behind before clicking into top gear against Dodin, who contributed to her own downfall with consecutive double faults when serving for a 5-3 lead.

Gauff, who has now won 22 of her last 23 matches on home soil, will face Caroline Garcia for a place in the quarter-finals after the Frenchwoman beat former world number one Naomi Osaka 7-6 (4) 7-5.

"Caroline's always a tough player to play," US Open champion Gauff said in her post-match press conference. "I think I lost to her the most recent time.

"She's tough. We all know how she plays. Takes the ball super early, plays very aggressive.

"I think for me it's going to be important that I just kind of stick to my game and get the ball deep in the court and not let her run me around on the court."

World number one Iga Swiatek had to come from behind as she saw off Czech teenager Linda Niskova 6-7 (7) 6-4 6-4.

The 19-year-old, who knocked Swiatek out of the Australian Open, came from a break down to win the opening set in a tie-break and had a break point to complete a comeback from 5-1 in the second set.

Swiatek held on and survived another late rally from Niskova to serve out the deciding set and book a last-16 clash with Ekaterina Alexandrova.
