Wally Masur has a competitive career record of 327–285 across 612 matches (53.4%). 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: Hong Kong, Adelaide, Newport.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Wally Masur is 65–48 (57.5%) across 113 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): Wally Masur is 17–21 (44.7%) across 38 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the calendar.
11 finals reached — won 3, lost 8 (27% conversion) — capable of reaching finals consistently, with room to improve at the decisive moment. 30 semifinals. 49 quarterfinals.
vs. Top 10: 7–62 (10.1%, 69 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: 79–62 (56.0%); best-of-three: 248–223 (52.7%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Dominant season: 1992 — 40–30 (57.1%) from 70 matches. That year represents a level of dominance that sets the ceiling for what Wally Masur can produce.
