Philip Johnson has found the Tour difficult, recording 8–15 across 23 matches (34.8%). 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): Philip Johnson is 2–2 (50.0%) across 4 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
vs. Top 10: 1–2 (33.3%, 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: 2–2 (50.0%); best-of-three: 6–13 (31.6%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 1989 — 5–7 (41.7%) from 12 matches. The best single-season display to date — a useful reference point as the career continues to develop.
