Quentin Halys, Sebastian Baez, and Mariano Navone each knocked out seeded opponents on Wednesday to headline a day of upsets at the Generali Open in Kitzbühel, setting up a compelling set of quarter-final matchups. The trio's wins reshuffled the draw and handed the clay-court event its most dramatic session of the week.
Halys Outclasses Second Seed Vacherot
Frenchman Quentin Halys delivered arguably his finest performance of the season, dismantling second seed Valentin Vacherot 6-3, 6-4 to reach the last eight. The 29-year-old is competing at Kitzbühel for the first time and has yet to drop a set in the tournament. He saved the only break point he faced throughout the match — a display of composure that underlined his fifth career win against a Top-20 opponent.
The victory advances Halys to his fourth tour-level clay-court quarter-final and ninth overall. 'I think I played well. One of the best matches of my year. I was serving quite well, and maybe he did not play his best match,' Halys said. 'But still, I am happy with how I played from the first point to the last. I was really focused, made many balls, and made him play many high balls.'
Vacherot, ranked World No. 19, was making only his second tournament appearance since withdrawing from Roland Garros in May due to a stress fracture in his foot. His match sharpness was visibly limited. Halys will next face Mariano Navone in the quarter-finals.
Navone Demolishes Struff in Straight Sets
Mariano Navone continued his imperious clay-court form, routing sixth seed Jan-Lennard Struff 6-0, 6-3. The Argentine, ranked No. 47 in the PIF ATP Rankings, has not conceded a set all week — a run that mirrors the confidence he built when claiming his maiden ATP Tour title in Bucharest in April. Navone has now accumulated 18 tour-level wins this season, matching his own records from both 2024 and 2025.
Baez Battles Through in Three Sets
Former Kitzbühel champion Sebastian Baez survived a stern test from third seed Arthur Rinderknech, prevailing 7-6(6), 2-6, 6-4 in a match that stretched to two hours and 27 minutes. Six of Baez's seven ATP Tour titles have come on clay, including his 2023 Kitzbühel title, and he remains a formidable threat on the surface. He will next face Germany's Yannick Hanfmann, who beat Marco Trungelliti 6-4, 7-6(2).
Seeds Buse and Etcheverry Also Progress
Not every seed stumbled. Fifth seed Ignacio Buse recovered from dropping the opening set to defeat Swiss qualifier Kilian Feldbausch 2-6, 6-2, 6-2. Fourth seed Tomas Martin Etcheverry was more comfortable, eliminating Austrian qualifier Jurij Rodionov 6-2, 7-6(4). The two seeds will square off against each other in the quarter-finals.
Quarter-Final Lineup
The Kitzbühel quarter-finals now feature: Halys vs Navone and Baez vs Hanfmann on one side of the draw, alongside Buse vs Etcheverry. With three seeds already eliminated and the remaining contenders in strong form, the last eight promises to be fiercely contested on the Tyrolean clay.
Point of View
Not just winning. Halys, on debut here and yet to drop a set, is the under-the-radar name worth watching — his record against Top-20 opponents is now five wins, and none of those came with a comfortable path. The real intrigue is whether Baez, a former champion on this court, can recapture that 2023 form against Hanfmann, who is playing with nothing to lose.
