The Miami Masters lost yet another Top 6 player today as home superstar Coco Gauff tumbled out to Russian Anastasia Potapova 6-7(10-8), 7-5, 6-2 in the third round.

The 19-year-old Gauff, rallied from 5-2 down in the first, then led by a set and 5-3 in the second before things unraveled as Potapova got her first win over the American in three tries. Gauff won just 41% of her second serves and converted just three of 13 break chances while Potapova won 10 of the last 12 games.

“I think I just let it go, and I started to focus on my tennis and going for my shots and not thinking what she is going to do,” Potapova said afterwards. “I’m really happy to be in the fourth round for the first time; it’s a dream that really came true.

“Coco is an unbelievable athlete and she has very good fitness. I’m really surprised that I could stay at the same level until the end.”

In a battle of Americans, No. 3 Jessica Pegula held off 30th-seeded Danielle Collins 6-1, 7-6(7-0).

Pegula lost only 8 points on first serve, faced just 2 break chances saving both while breaking serve three times in the match, all in the first set. She won 12 of the last 14 points of the match including a bagel breaker to win it.

Pegula has never lost to Collins, leading 2-0 in tour-level head-to-head battles.

Elsewhere on Saturday, No. 10 seed Elena Rybakina had to battle to get past No. 21 seed Paula Badosa 3-6, 7-5, 6-3. The Indian Wells winner had to save a match point on serve at 4-5 in the second. She has now won her last 10 matches.

“It didn’t start well in the first set but in the end I just found some energy,” Rybakina said to the WTA. “I was trying to push more on the serve and started to move better on the court.”

“It was a really tough battle. I was trying to focus on every point because the first set didn’t go my way, but it was just a few mistakes here and there. Overall, I played well. Paula was serving well. Just happy that I was able to manage in three sets.”

The powerful 20-year-old Qinwen Zheng upended 12th-seeded Liudmila Samsonova 5-7, 7-6(7-5), 6-3 taking the last six games. No. 20 seed Magda Linette bounced the last former champion let, Victoria Azarenka, 7-6(7-3), 2-6, 6-4. Former runner-up Jelena Ostapenko and the 25th-seeded Martina Trevisan also won.
