Jan-Michael Gambill has a competitive career record of 201–196 across 397 matches (50.6%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher. Claimed 3 titles: Scottsdale, Delray Beach.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Jan-Michael Gambill is 25–31 (44.6%) across 56 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): a positive 46–41 (52.9%) across 87 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
7 finals reached — won 3, lost 4 (43% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 15 semifinals. 40 quarterfinals.
vs. Top 10: 13–38 (25.5%, 51 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: 26–35 (42.6%); best-of-three: 175–161 (52.1%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Peak season: 2001 — 35–25 (58.3%) from 60 matches. That year captures the ceiling of what Jan-Michael Gambill can do when performing at their best and represents the standard to aim for.
