Diego Perez has a competitive career record of 223–235 across 458 matches (48.7%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher. Claimed 1 title: Bordeaux.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Diego Perez is 15–21 (41.7%) across 36 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): Diego Perez has struggled at Masters level: 1–4 (20.0%) in 5 matches. Improving at this level is the clearest path to a stronger overall record.
2 finals reached — won 1, lost 1 (solid 50% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 12 semifinals. 36 quarterfinals.
vs. Top 10: 7–26 (21.2%, 33 matches). Top 10 opponents have represented a clear ceiling; addressing that deficit is the single biggest lever for improving the overall record.
By format — best-of-five: 41–40 (50.6%); best-of-three: 182–195 (48.3%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Peak season: 1986 — 32–27 (54.2%) from 59 matches. That year captures the ceiling of what Diego Perez can do when performing at their best and represents the standard to aim for.
