MIAMI — Roberto Bautista Agut didn’t take the easiest route to the Miami Open quarterfinals.
The No. 7 seed from Spain fought off a match point before ousting former Miami champion and No. 18 seed John Isner of the U.S. 6-3, 4-6, 7-6 (7) – his second three-set win in as many matches so far in the tournament.
Bautista Agut will face either top-seeded Daniil Medvedev of Russia or unseeded Frances Tiafoe of the U.S. in the quarterfinals.
Bautista Agut lost the first point of the third-set tiebreaker on his serve, giving the big-hitting Isner the early edge. Isner lost the mini-break by putting a forehand into the net five points later, then gave himself match point after a 138 mph ace for a 6-5 edge.
Bautista Agut wasn’t fazed, won three of the last four points and escaped.
“He makes always difficult matches playing against him,” Bautista Agut said. “He has a very big serve and a lot of power from baseline with the forehand. It makes it always difficult, no?”
It was Isner’s earliest Miami exit since 2017, when he lost in the third round. He won the tournament in 2018 and lost the final in 2019 to Roger Federer in straight sets.
No. 21 seed Jannik Sinner of Italy breezed to the quarterfinals with a 6-3, 6-2 win over Emil Ruusuvuori of Finland. All eight of the men’s round-of-16 matches were set to be played Tuesday – Isner was one of four U.S. men to reach that round – as was a women’s quarterfinal between top-seeded Ash Barty and seventh-seeded Aryna Sabalenka.
ASTANA, Kazakhstan — Carlos Alcaraz’s first match as the No. 1-ranked player ended with a straight-set loss to David Goffin at the Astana Open.
The 19-year-old Spaniard lost 7-5, 6-3 in his first tour match since winning the U.S. Open and capturing the No. 1 ranking.
“David was playing really, really well. To come back to competition is never easy,” Alcaraz said. “It’s really tough for me, for my confidence.”
Alcaraz came from 5-2 down to level the first set at 5-5, only to be broken again by his Belgian opponent.
“When you play against the World No. 1 on a big stage, big crowd, the fire inside gives you so much power to play your best tennis because you don’t have any choice,” Goffin said. “You have to fight and give your best and that was the case today.”
Second-seeded Daniil Medvedev and No. 3-seeded Stefanos Tsitsipas both avoided similar upsets. Medvedev beat Albert Ramos-Vinolas of Spain 6-3, 6-1 and Tsitsipas ousted Kazakhstan’s Mikhail Kukushkin 6-3. 6-4.
OSTRAVA, Czech Republic — Fifth-seeded Daria Kasatkina defeated 2021 U.S. Open champion Emma Raducanu 7-5, 6-4 to advance to the second round of the Agel Open.
Kasatkina was playing her first match since losing in the first round of the U.S. Open and will next face Ekaterina Alexandrova.
Sixth-seeded Belinda Bencic of Switzerland rallied to eliminate former top-five player Eugenie Bouchard of Canada 6-7 (7), 6-1, while Aliaksandra Sasnovich upset eighth-seeded Jelena Ostapenko 6-2, 6-2.
American qualifiers Alycia Parks and Catherine McNally both advanced. Parks upset Czech Karolina Pliskova 6-0, 7-6 (3) and McNally eased past Anna Blinkova 6-1, 6-2 at the indoor hardcourt event in the Czech eastern city of Ostrava.
