Josselin Ouanna has found the Tour difficult, recording 9–17 across 26 matches (34.6%). The numbers point to a player still building their Tour presence — a key area of opportunity going forward.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Josselin Ouanna is 4–5 (44.4%) across 9 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.

By format — best-of-five: 4–5 (44.4%); best-of-three: 5–12 (29.4%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 2010 — 4–5 (44.4%) from 9 matches. The best single-season display to date — a useful reference point as the career continues to develop.
