Sergio Cortes has found the Tour difficult, recording 18–26 across 44 matches (40.9%). 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): 2–1 across just 3 matches — still very early days at this level.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): a positive 2–2 (50.0%) across 4 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
By format — best-of-five: 7–6 (53.8%); best-of-three: 11–20 (35.5%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 1993 — 9–8 (52.9%) from 17 matches. The best single-season display to date — a useful reference point as the career continues to develop.
