Tennis Prediction Raphaël Collignon vs Lorenzo Sonego: Gstaad

Gstaad 🇨🇭

• The over 10.5 games S1 between Raphaël Collignon and Lorenzo Sonego seems to me to be a real opportunity today in Gstaad.

• The starting point is this: the two men have never faced each other on the main circuit. No H2H, no benchmarks, no tactical keys already found. A first set between two players discovering each other, it rarely settles in three games.

• And the setting amplifies everything: Gstaad is the highest tournament in Europe, 1050 meters of altitude. The ball flies in the rarefied air, the bounce is very high, and on this clay court the servers are protected like nowhere else on the surface.

• The figure is eloquent: on this tournament, players hold their serve 78.3% of the time, almost three points above the clay court average. On a surface supposed to reward the returner, the logic is reversed.

• I want to give the best argument against me right away: Collignon is the favourite, he is on a winning streak and has a very positive record on clay this season.

• On the other hand, Sonego is going through a difficult year on the surface, eliminated early from each of his clay court tournaments in 2026. An early break by the Belgian and this first set will close without ever opening.

• But that's where I don't agree with the market. It's not Sonego's baseline game that decides the length of this set, it's his serve. And his serve, he has no problem with.

• In the first round against Joel Schwaerzler, the Italian was not broken once. Not once. Two break points conceded in 1h50, both saved.

• Collignon, on the other hand, had to go three sets and 32 games against Timofey Skatov, an opponent who was largely within his reach on paper. A match where he actually lost the first set.

• The Belgian served 17 aces that day, which says everything about the benefit of altitude on his serve. But also 10 double faults, two breaks conceded and 9 break points conceded.

• He is a serving profile that makes a lot of free points but also offers openings. In both directions, the game counter turns.

• The statistics since the start of the tournament remain quite eloquent.

• Sonego himself acknowledged after his first round that the adaptation from the grass season was tough and that the very high bounce was bothering him.

• A player who is still finding his bearings in the rally but holding his serve, that's exactly the
