Raphael Collignon vs Valentin Vacherot Prediction 17 July 2026

Raphael Collignon enters this quarterfinal after making a strong start at the Gstaad clay-court tournament. The Belgian secured a confident straight-set victory over Lorenzo Sonego (2-0) in the previous round after overcoming Timofey Skatov in a more competitive match (2-1). Although his recent results before Gstaad were less consistent, including defeats against Felix Auger-Aliassime at Wimbledon (0-3), Juan Manuel Cerundolo in Eastbourne (1-2), and Alexander Zverev in Halle (0-2), Collignon has shown that clay remains one of his most comfortable surfaces. His heavy baseline game, physical strength, and ability to maintain intensity in long rallies make him a difficult opponent on slower courts.

Valentin Vacherot has also reached the quarterfinal stage after a challenging opening match against Yannick Hanfmann, where he managed to recover and secure a victory (2-1). The Monaco player has demonstrated strong fighting ability throughout the season, including a solid run at Roland Garros where he defeated Terence Atmane (3-1). However, his overall recent form has been inconsistent, with defeats against Alejandro Tabilo at the French Open, Emilio Nava in Madrid, and Carlos Alcaraz in Monte Carlo. While Vacherot possesses good defensive qualities and can compete in long exchanges, maintaining a high level throughout matches remains a concern.

From a tactical perspective, this matchup is likely to be decided by Collignon’s ability to control rallies with his powerful groundstrokes and apply constant pressure from the baseline. Vacherot will look to extend points and force errors through consistency, but the Belgian’s aggressive style and comfort on clay should allow him to dictate more of the important exchanges.

A competitive quarterfinal is expected, but Collignon’s recent performances in Gstaad and his stronger clay-court profile give him a clear advantage. If he continues to play with the same intensity shown against Sonego, he should be able to overcome Vacherot’s resistance and secure another victory on home European clay. Consequently, the projection points toward Collignon advancing to the semifinal.
