One final reached, converted into a title — a perfect finals record so far. 4 semifinals. 7 quarterfinals.
vs. Top 10: 2–19 (9.5%, 21 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: 15–17 (46.9%); best-of-three: 73–124 (37.1%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 1982 — 16–22 (42.1%) from 38 matches. The best single-season display to date — a useful reference point as the career continues to develop.
