Raphaël Collignon Advances to Gstaad Quarterfinals After Defeating Lorenzo Sonego
Belgian tennis player Raphaël Collignon secured a significant victory at the EFG Swiss Open Gstaad on Wednesday, defeating Italian veteran Lorenzo Sonego in straight sets. The 22-year-old, currently ranked No. 42 in the ATP live rankings, navigated the clay courts of the Roy Emerson Arena to overcome his opponent 7-6(4), 6-4, marking a notable progression in his professional career.
Match Summary and Performance Metrics
The match, which lasted just over two hours, saw Collignon display composure under pressure against the 83rd-ranked Sonego. In the opening set, the Belgian maintained consistency on his service games, eventually edging the tie-break 7-4. The second set followed a similar trajectory, with Collignon securing a critical break of serve to close out the match.

Collignon’s performance relied on a high first-serve percentage and aggressive baseline play, a strategy that neutralized Sonego’s attempts to dictate points. According to official ATP match statistics, Collignon’s ability to convert break points at key moments proved the difference in a contest where both players struggled with consistency on their second serves.
Advancing to the Next Round in Gstaad
With this win, Raphaël Collignon advances to the quarterfinals of the ATP 250 tournament in Gstaad, Switzerland. He is scheduled to face the winner of the second-round match between Valentin Vacherot and Yannick Hanfmann. This upcoming encounter represents a potential path to the semifinals for the rising Belgian talent, who has spent the majority of the current season refining his game on the ATP Challenger Tour before finding success in these higher-tier events.
Context of the EFG Swiss Open
The EFG Swiss Open Gstaad remains a prestigious fixture on the ATP Tour, held annually at an altitude of approximately 1,050 meters. The unique conditions—characterized by thinner air and faster ball movement compared to sea-level clay court events—often favor players who can adapt their spin and pace effectively. For Collignon, reaching the final eight in Gstaad serves as a validation of his recent form and his transition into the top-50 tier of men’s professional tennis.

Sonego, a former top-30 player, entered the tournament looking to regain momentum after a challenging mid-season stretch. His exit in the second round continues a difficult period for the Italian, who has struggled to find his rhythm on European clay throughout the summer months.
Tournament Outlook
The remainder of the tournament bracket will be finalized following the conclusion of all second-round matches. Collignon’s next match is expected to be scheduled for Friday, pending the completion of the Vacherot-Hanfmann fixture. Official updates regarding the match schedule and court assignments will be posted via the ATP Tour’s central communications portal as tournament organizers finalize the quarterfinal draw.
