Jan Gunnarsson has a competitive clay court record of 88–97 across 185 matches (47.6%). The record shows a player capable of competing here, though there is clear room to push the win rate higher. Jan Gunnarsson has reached 2 finals without yet claiming a title on clay — one of the finest margins in tennis.

At Grand Slam level (Roland Garros): Jan Gunnarsson is 12–10 (54.5%) across 22 Grand Slam matches — below .500, though the elite draw depth at the Slams makes that a notoriously difficult barrier to crack.

ATP Masters 1000 on clay (Monte Carlo, Madrid, Rome): Jan Gunnarsson is 2–3 (40.0%) across 5 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the whole clay swing.

2 finals reached on clay — none converted into a title yet. Reaching 2 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 4 semifinals. 14 quarterfinals.

vs. Top 10 on clay: 1–17 (5.6%, 18 matches). Top 10 opponents have represented a clear ceiling on clay; addressing that deficit is the single biggest lever for improving the overall record here.

By format on clay — best-of-five: 12–10 (54.5%); best-of-three: 76–87 (46.6%). Slightly better in five-set matches on clay — a positive sign for the Slams specifically.

Best season: 1985 — 12–8 (60.0%) from 20 matches. The best single-season display to date — a useful reference point as the clay record continues to develop.
