Surface breakdown: where the edge lives

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	48	60.4%
Masters 1000	39	48.7%
ATP 500	39	48.7%
Grand Slam	21	42.9%

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
R1	59	61.0%
R2	25	56.0%
R3	11	36.4%
R16	30	53.3%
QF	16	31.2%
SF	5	20.0%
F	1	0.0%

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
Fritz	2–2	50.0%
Cerundolo	2–2	50.0%
Tien	3–1	75.0%
Medvedev	0–4	0.0%
Ofner	1–2	33.3%

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 Alex Michelsen

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: 89 matches with usable prices). Uncertainty rises when the next match is on grass or in a deep-draw round where Michelsen's historical conversion collapses.
