(Monte-Carlo) Jan-Lennard Struff advanced to the quarter-finals of the Monte-Carlo Tennis Masters on Thursday after upsetting fourth seed Casper Ruud 6-1, 7-6 (6).

Struff, a qualified player, thus continued his rise following a serious injury.

The German, once ranked 29etumbled to 168e level after suffering a foot injury last year during a game at the Miami Masters — an injury that forced him out of the league for more than two months.

Struff is having a strong start to the season and cracked the top 100 again last month, but he hadn’t beaten a top 10 player in the world this season before clashing with Ruud on Monaco clay.

His aggressive style allowed him to get 37 winners and 23 points at the net against the Norwegian, who suffered four service breaks.

Struff also ended Ruud’s nine-game winning streak on clay. The finalist at the French Open in 2022 has won his last two tournaments on this playing surface: in Gstaad, in July, and in Estoril, last week.

Struff will now face Russian Andrey Rublev, who defeated his compatriot Karen Khachanov 7-6 (4), 6-2.

“We know each other well. It was all in the head in the first round. We didn’t play great tennis, Rublev said. But it was difficult to do so because of the wind, which was very strong, and the court, which was slippery, so it was difficult to raise the level of play.

On the other hand, seventh-seeded Jannik Sinner came from behind and spurned seven match points against him to overthrow the 10e seeded Hubert Hurkacz 3-6, 7-6(6), 6-1.

Sixth seed Holger Rune reached the quarter-finals without even having to make a single swing with his racquet, as Italian Matteo Berrettini withdrew from the tournament due to injury.

Sinner emerged victorious in a 22-shot rally as he trailed 6-5 in the tiebreaker to stay in the game. Hurkacz lost the next two points and threw his racquet in frustration, before losing his temper completely in the third set.

“I knew I was going to have a hard time finding my rhythm against him,” Sinner said of Hurkacz. He was very effective on serve in the first set and a half, but when I broke him for the first time in the match, the tide turned. »

World No. 1 Novak Djokovic will take on Italian Lorenzo Musetti later today, while third seed Daniil Medvedev will face No. 13.e seeded Alexander Zverev.

Rafael Nadal and world No. 2 Carlos Alcaraz withdrew from the tournament last week, as did Quebecer Félix Auger-Aliassime. Nadal won the Monte Carlo Masters a record 11 times, including eight in a row between 2005 and 2012. The holder of 22 career Grand Slam titles has been plagued by a left hip flexor tendon injury since the Australian Open.
