Jan-Lennard Struff delivered a dominant performance to defeat Hugo Grenier in straight sets, confirming his status as the clear favorite in their first-round encounter at the Rotterdam ATP 500.
First Set: Struff Dominates from the Start
The opening set was a one-sided affair, with Struff asserting his authority immediately. The German was flawless on serve and relentless in return games, breaking Grenier three times and racing through the set 6–0.
Grenier, who had narrowly survived the opening round of qualifying by saving a match point against Dutch outsider Tallon Boogaard, struggled to find any rhythm. Struff gave him no opportunities, conceding no break points and dictating play from the first ball.
The difference in level was clear, with Struff striking 12 winners in the set compared to just 2 from a visibly out-of-sorts Grenier.
Second Set: Grenier Shows Resistance, Struff Finishes Strong

Struff continued his momentum early in the second set, breaking serve to move ahead 2–0. Grenier responded immediately with a break back, showing improved energy and beginning to compete on more even terms.
From that point on, the Frenchman held his own, matching Struff game for game until 5–4. Serving to stay in the match, Grenier was unable to maintain his level under pressure, and Struff stepped in once more to secure the decisive break.
Numbers Reflect Struff’s Superiority
Struff closed out the match 6–0, 6–4, advancing comfortably to the next round.
The statistics underlined his dominance across the contest. Struff finished with 21 winners compared to just 5 from Grenier, while also committing fewer unforced errors (17 to 23). The German’s consistency and firepower proved decisive throughout.
