Friday's Gstaad quarterfinal pits Raphael Collignon against Valentin Vacherot on clay. Raphael Collignon is 6-4 across recent matches. Valentin Vacherot brings a 3-match winning streak into this one, 6-4 across the last ten.
The two have never played — a first meeting always adds a layer of uncertainty the numbers can't fully capture.
On paper it's close: comparable ratings, comparable serve numbers, small margins everywhere. A tiebreak or two would surprise nobody, with Collignon fractionally more likely to land the big points.
