Magnus Gustafsson holds a solid career record of 415–260 across 675 matches (61.5%). A winning majority across 675 matches shows consistent ability to get results on Tour. With 14 titles, among the most prolific champions in the Open Era: Auckland, Dubai, St. Petersburg, Bastad and 6 more.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Magnus Gustafsson is 42–41 (50.6%) across 83 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 58–38 (60.4%) across 96 matches — winning above .500 at this level, week in week out, is a genuine sign of quality.
27 finals reached — won 14, lost 13 (solid 52% conversion) — consistently getting to finals and winning the majority is a hallmark of elite performers. 43 semifinals. 87 quarterfinals.
vs. Top 10: 19–47 (28.8%, 66 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: 53–55 (49.1%); best-of-three: 362–205 (63.8%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Dominant season: 1991 — 52–17 (75.4%) from 69 matches. That year represents a level of dominance that sets the ceiling for what Magnus Gustafsson can produce.
