Kristof Vliegen has found the Tour difficult, recording 89–122 across 211 matches (42.2%). The numbers point to a player still building their Tour presence — a key area of opportunity going forward. Kristof Vliegen has reached 2 finals without yet claiming a title — one of the finest margins in tennis.
At Grand Slam level (Australian Open, Roland Garros, Wimbledon, US Open): Kristof Vliegen has struggled at Grand Slam level: 9–23 (28.1%) in 32 matches. The best-of-five format and elite fields make this the toughest benchmark on Tour.
ATP Masters 1000 (Indian Wells, Miami, Monte Carlo, Madrid, Rome, Canada, Cincinnati, Shanghai, Paris): Kristof Vliegen is 14–17 (45.2%) across 31 Masters matches — below .500 in the Tour's deepest fields. Lifting that record here would unlock better results across the calendar.
2 finals reached — none converted into a title yet. Reaching 2 finals is a mark of real quality, but the gap between finalist and champion is one of the finest lines in the sport. 6 semifinals. 14 quarterfinals.
vs. Top 10: 4–17 (19.0%, 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: 14–27 (34.1%); best-of-three: 75–95 (44.1%). Markedly stronger in three-set formats; the win rate drops noticeably in five-setters, which has direct implications for Grand Slam performance.
Peak season: 2006 — 32–23 (58.2%) from 55 matches. That year captures the ceiling of what Kristof Vliegen can do when performing at their best and represents the standard to aim for.
