BREAKDOWN · MODEL ANALYSIS

The model makes A. Gea the favorite with a 60% win probability, against M. Zheng's 40% — a solid favorite, though Zheng keeps real chances. Converted to odds, that probability is worth about @1.68; the offered odds are around @2.26 (a 44% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #87 vs #107 (better ranked); 1-0 in favor; performs +12% above baseline (67% career on the surface); model 60% vs market 44% → the model sees it as more likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 60%, 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 40 out of every 100 times Zheng 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.
