A. Gea vs Z. Zhang — prediction

Warm: the ball flies a little more and fitness counts.
Humid air: the ball loses some speed.
Light wind: no noticeable effect.
Surface feeds the model (surface specialization is one of its factors). Weather and altitude are context we publish for you — they do NOT move the probability.

›Hard specialist: performs +12% above baseline (67% career on the surface)
›Model 70% vs market 78% → the model sees it as less likely than the odds
›Recent form: 8/10 in recent matches
›On a streak: 2 wins in a row
The model makes A. Gea the favorite with a 70% win probability, against Z. Zhang's 30% — a solid favorite, though Zhang keeps real chances. Converted to odds, that probability is worth about @1.43; the offered odds are around @1.29 (a 78% implied), slightly below the market, so the model is a touch more cautious.
Several factors explain the number: #58 vs #165 (better ranked); performs +12% above baseline (67% career on the surface); model 70% vs market 78% → the model sees it as less likely than the odds; 8/10 in recent matches.
Read it with perspective. Our probability is calibrated — when the model says 70%, that outcome happens roughly that percentage of the time, with ~65% out-of-sample accuracy — but being the favorite is not being the winner: roughly 30 out of every 100 times Zhang wins. The model also tends to agree with the market, so the odds already capture almost all the edge: don't take it as a sure value.
