Zan Guerry has found the Tour difficult, recording 39–75 across 114 matches (34.2%). 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): Zan Guerry is 4–6 (40.0%) across 10 Grand Slam matches — below .500, though the elite draw depth makes that a notoriously difficult barrier.
vs. Top 10: 0–7 (0.0%, 7 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: 3–7 (30.0%); best-of-three: 36–68 (34.6%). Slightly stronger in three-set contests, though the five-set record is still respectable.
Best season: 1969 — 8–10 (44.4%) from 18 matches. The best single-season display to date — a useful reference point as the career continues to develop.
