Surface is the first filter before round or opponent quality. Compare clay baselines in the clay-court betting guide and grass patterns in the grass-court specificity guide when translating these rates into match previews.

Tournament tier: reliability by event level

Tournament level	Matches	Win rate
ATP 250	25	52.0%

ATP 500	40	42.5%
Grand Slam	20	35.0%

Grand Slam and Masters samples matter most for pricing; ATP 250/500 volume often inflates or deflates the headline win rate. Cross-check against Tommy Paul or Francisco Cerundolo for other ranks-21–50 archetypes.

Round-by-round: early rounds vs deep runs

Round	Matches	Win rate

R3	6	16.7%

SF	4	75.0%

Round curves separate true closers from early-round specialists. Use the drop from early rounds into deeper stages as a fade signal even when the overall win rate looks acceptable — the same structural idea as Rublev's late-round ceiling.

H2H against elite rivals

Rival	W–L	Win rate
Djere	1–2	33.3%
Rublev	2–1	66.7%
Diallo	1–2	33.3%
Borges	3–0	100.0%
Humbert	2–1	66.7%

Elite H2H is sparse for many mid-ranked players; only rows with multiple meetings are shown. Use these as matchup modifiers, not as a substitute for surface form.

How our model treats Zizou Bergs

The ensemble weights surface win-rate history, recent form (last 5 / last 10), and tournament-tier context most heavily for a rank-21–50 profile like this. Favourite/underdog conversion is a secondary prior when odds history is dense enough (here: 59 matches with usable prices). Uncertainty rises when the next match is on indoors or in a deep-draw round where Bergs's historical conversion collapses.
