Yasufumi Yamamoto
Yasufumi Yamamoto has found the Tour difficult, recording 9–17 across 26 matches (34.6%). The numbers point to a player still building their Tour presence — a key area of opportunity going forward.
By format — best-of-five: 5–5 (50.0%); best-of-three: 4–12 (25.0%). Significantly better in five-set matches — a strong physical profile that tends to tell as matches and tournaments progress.
Best season: 1994 — 5–3 (62.5%) from 8 matches. The best single-season display to date — a useful reference point as the career continues to develop.
