Jean-Loup Rouyer has a competitive career record of 66–69 across 135 matches (48.9%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Jean-Loup Rouyer is 12–16 (42.9%) across 28 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
By format — best-of-five: 17–27 (38.6%); best-of-three: 49–42 (53.8%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Best season: 1970 — 18–14 (56.3%) from 32 matches. The best single-season display to date — a useful reference point as the career continues to develop.
