Blockx serves through a rib injury to make Belgian history
In other matches on Monday, Alexandre Bloks went three sets without serving and still became the first Belgian to reach the quarter-finals of the US Open, defeating 24th seed Francisco Cherundolo of Argentina 6-3, 4-6, 7-5, 7-5. The Belgian number 28 is 21, which also makes him the youngest Belgian to reach a Grand Slam singles quarter-final in the Open era, on his US Open main draw debut and his first Grand Slam.
“Physically, today was a real struggle on the court,” he said. “I struggled a lot with my rib, especially when serving. It got worse throughout the match. In the end, the doctor gave me some medicine that really helped me until the end of the third set, where in the fourth set I could finally serve like I normally do.” What happens next is not regulated. “During those first three sets, I was really worried because I had a really sharp pain in my rib. I feel good right now. I’ve had some treatment, some medication, so hopefully it stays that way and will be better tomorrow and the next game.”
He has already eliminated Italian No. 5 Flavio Cobolli 6-7 (4), 6-3, 6-0, 6-3, after Argentina’s Marco Trungelliti 6-3, 6-2, 3-6, 6-1 and Chile’s Tomas Barrios Vera 6-3, 6-4, 6-6. Cherundolo, ranked No. 25, is now 0-4 in Grand Slam fourth rounds and one win shy of joining Thomas Martin Etcheverry as the only active Argentines to reach a grand quarterfinal. He beat American No. 9 Taylor Fritz 3-6, 4-6, 6-3, 6-4, 6-4 in two sets, after Germany’s Jan-Lennard Struff 5-7, 7-5, 4-6, 6-2, 6-3 and Austria’s Philipp Misolic 6-4, 6-4, 6-4.
Khachanov is down two sets to one against Tien
Blockx’s future opponent Karen Khachanov, seeded 50th and coming from behind, came from two sets down to American 14th seed Sovorogh Thien to win 7-5, 4-6, 6-7 (6), 6-1, 6-4 in just under four hours on a court that wanted the other result. It is his seventh Grand Slam quarter-final and first since reaching the semi-finals here four years ago. Tien, 20, was in tears at the end.
Russ set more of a choice than a level. “It’s always a game where you go in more, take risks or decide to play it safer and you push the guy to kind of let it go. I’m so glad I messed around a lot. I was trying to dominate from the start. He was generous with what he was up against. “Super talented guy. He passed me several times. It’s unbelievable from running all over the court, rebounding extra balls.”
Khachanov defeated Canadian No. 3 Felix Auger-Aliasime 6-7 (5), 6-3, 6-2, 6-2, France’s Benjamin Bonzi 6-3, 6-2, 6-4 and Argentina’s Roman Andres Buruchaga 6-3, 6-0, 6-. Tien, who beat Czech Jakub Mensik 6-3, 1-6, 6-7 (2), 6-3, 6-4, France’s Gael Monfils 6-3, 6-4, 6-3 and Portugal’s Nuno Borges 6-4, 6-1, 6-2, was last. his loss in the quarterfinals left him with three instead of four, which would have been the first since 1995.
