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	21	71.4%
Grand Slam	59	71.2%

Grand Slam and Masters samples matter most for pricing top-20 players; ATP 250/500 volume can inflate or deflate the headline win rate. Cross-check against Jannik Sinner or Alexander Zverev for peer archetypes.

Round-by-round: early rounds vs deep runs

Round	Matches	Win rate
R1	35	82.9%
R2	59	64.4%
R3	26	80.8%
R16	63	61.9%
QF	38	60.5%
SF	24	75.0%
F	18	38.9%

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 elite — the same structural idea as Rublev's late-round ceiling.

H2H against elite rivals

Rival	W–L	Win rate
Cerundolo	4–5	44.4%
Munar	6–1	85.7%
Rune	4–2	66.7%
Djokovic	2–3	40.0%
Auger Aliassime	2–3	40.0%

Elite H2H is the matchup modifier on top of surface form. Prefer rows with multiple meetings; single-sample rivalries are noise.

How our model treats Casper Ruud

The ensemble weights surface win-rate history, recent form (last 5 / last 10), and tournament-tier context most heavily for a top-20 profile like this. Favourite/underdog conversion is a strong secondary prior when odds history is dense (here: 205 matches with usable prices). Uncertainty rises when the next match is on grass or in a deep-draw round where Ruud's historical conversion collapses.
