Gary Donnelly has found the Tour difficult, recording 13–32 across 45 matches (28.9%). 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): Gary Donnelly is 4–5 (44.4%) across 9 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
vs. Top 10: 0–3 (0.0%, 3 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: 4–6 (40.0%); best-of-three: 9–26 (25.7%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 1986 — 11–11 (50.0%) from 22 matches. The best single-season display to date — a useful reference point as the career continues to develop.
