Russia's men advanced to the quarters with a straight-set victory over top-seeded Daniel Medvedev Tiafoe.
World No.1 Australia's Ash Barty won the final nine points after beating seventh seed Sabalenka in the three-set women's quarter-finals on Tuesday, while Russia's men advanced to the quarters with a straight-sets victory over top seed Daniel Medvedev Tiafoe. – Part of a day where the American men's contingent was paraded from four to one, with Sebastian Korda remaining 16 rounds for the US.
The 20-year-old Korda defeated Argentine fifth seed Diego Schwartzman 6-3, 4-6, 7-5 for the biggest win of his career so far. And it would make for an interesting Thursday for the Korda family: He would be in the Miami quarterfinals that day, while his sisters Jessica and Nellie would be playing in the first round of the first female golf major of the year, the ANA Inspiration.
"Sebi is a man who is going to be special, man," Tiafoe said.
Korda, whose father Petr Korda reached number 2 in the world during his illustrious career, attended the show to appease the evening crowd. He was broken in the third quarter at 5-4 to expect from Schorpzman, then responded by breaking Argentina to the right and finally being out of the match.
By then, it was perhaps a little colder than the brutal conditions that the players had endured in the day's session – but tough nonetheless, which Korda appreciated.
Korda faced fourth seed Andre Rublev of Russia in the quarter-finals, saying, "I love the heat and I love the humidity. The more humid it is, the more humid it is."
Rublev defeated Marin Cilic 6-4, 6-4 on Tuesday night.
After some initial cloud sorting and strong sunshine, the afternoon temperature reached the mid-80s Fahrenheit (upper 20 ° C) at Hard Rock Stadium and the humidity made it feel even warmer.
Barty outscored Sabalenka 6-4, 6-7 (5), 6-3, not bowing out for a third three-set win in four matches in the tournament. Medvedev defeated Tiafoe 6-4, 6-3 and trailed 10–1 against the US in their last four head-to-head matchups.
"There are different situations everywhere in the world and many times it suits you more than other places," Barty said.
"I think these are very familiar circumstances for me. With the heat and humidity, it's similar to Brisbane, where I grew up and was born and bred and trained all my life." Barty faced seven break points in the match and saved them all. She will take on No. 5 seed Elena Svitolina in the semi-finals on Thursday; Switolina defeated Anastasija Sevastova 6-3, 6-2 on Tuesday night to make it to the Final Four in Miami.
Barty is now 18–3 in his last 21 three-seters, 10–1 in his last 11 quarterfinal matches, and 12–3 in his last 15 meetings against fellow top-10 players. And he went on to win 10 matches in Miami.
"I enjoy these courts," Barty said.
"You know, I enjoy balls and how responsive they are to spin. A lot of different elements. But, you know, there are a lot of places around the world, which I like to play, and here is one of them." Tiafoe was a quarter finalist in Miami in 2019 and could not repeat the feat, nor could John Isner. He wasted the match point during the third set tiebreak and lost to seventh seed Roberto Bautista Agut 6-3, 4-6, 7-6 (7) of Spain.
Bautista Agut will face Medvedev in the quarter-finals. Medvedev hit 11 aces and showed no signs of wear until two days after the summer cramps during the third round win.
"I think we were both really tired, but I think we made an amazing show. I was really happy with my performance today," Medvedev said.
It was Isner's first Miami exit since 2017, when he lost in the third round. He won the tournament in 2018 and lost the final in straight sets to Roger Federer in 2019.
"That always makes it difficult to play matches against him," said Bautista Agut. "He has a very big serve and a lot of power from the forehand. It's always difficult, no?" Tiafoe needed a medical timeout in the second set of his match, taking a toll between heat and humidity. It was a break at that time, and the match just slipped from there.
"I felt that I couldn't really breathe," Tiafoe said.
"I felt like my heart is beating out of my chest. I was burying a lot, couldn't really sort myself out. I've done a lot, haven't discussed it a lot during these matches, but obviously That today it was out of control. " US 22nd seed Taylor Fritz also lost 6-7 (5), 6-3, 6-4 to No. 32 Alexander Bublik of Kazakhstan. Bublik will take on Italy's No. 21 seed Jannik Sinar in the quarter-finals; Sinar won 6-3 6-2 over Emil Rusuvuri of Finland.
Poland's No. 26 seed Hubert Hercz took a slight lead over Canada's No. 12 Milos Raonic 4-6, 6-3, 7-6 (4). Hurkez are out of the quarters to face No. 2 seed Stephanos Tsitipas of Greece 6-2, 7-6 (2) from Italy's No. 24 Lorenzo Songo in the final match on Tuesday night.
