Sergei Bubka has a competitive career record of 14–16 across 30 matches (46.7%). The record shows a player capable of competing at Tour level, though there is clear room to push the win rate higher.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): 1–1 across just 2 matches — still very early days at this level.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): Sergei Bubka has struggled at Masters level: 1–2 (33.3%) in 3 matches. Improving at this level is the clearest path to a stronger overall record.
By format — best-of-five: 5–5 (50.0%); best-of-three: 9–11 (45.0%). Slightly better in five-set matches — a positive sign for Grand Slam campaigns specifically.
Best season: 2011 — 3–4 (42.9%) from 7 matches. The best single-season display to date — a useful reference point as the career continues to develop.
