Struff regains his touch to stun Ruud and reach Monte Carlo Masters quarter-finals

German qualifier Jan-Lennard Struff upset fourth-seeded Casper Ruud 6-1, 7-6 (8-6) to reach the quarter-finals of the Monte Carlo Masters on Thursday.

Ranked 29th in the world, Struff dropped as low as No 168 after sustaining a foot fracture last year in Miami, an injury that left him sidelined for more than two months.

Struff has enjoyed a good start to the season and returned to the top 100 last month but had not beaten anyone in the top 10 since June 2021.

On Thursday, his aggressive style of play resulted in 37 winners and 23 points won at the net against Ruud, who dropped his serve four times and saw his nine-match winning streak on clay come to an end. The 2022 French Open runner-up had won his past two tournaments on the surface, in Gstaad last July and in Estoril last week.

Struff will next be up against 2021 runner-up Andrey Rublev, who beat Karen Khachanov 7-6 (7-4), 6-2.

“We know each other too well," Rublev said. "The first set was only mental. We didn’t show some tennis skills. But it was tough to show skills because the wind was really hard and the court was slippery and it was tough to do something.”

Meanwhile, Jannik Sinner was made to toil by Hubert Hurkacz as the Italian seventh seed saved a match point to seal a 3-6, 7-6 (8-6), 6-1 victory and book his spot in the last eight.

Watched on by sprint great Usain Bolt in the stands, Hurkacz raced to a 3-0 lead before Sinner got on the board and the world No 13 wobbled towards the end of the opening set before wrapping it up with two fiery first serves.

Sinner, a Monaco quarter-finalist last year as well, found himself in more hot water shortly after the second set began but the 21-year-old hit back after dropping serve to grab a break and level at 2-2.
