BREAKDOWN · MODEL ANALYSIS

The model makes N. Osaka the favorite with a 67% win probability, against S. Bejlek's 33% — a solid favorite, though Bejlek keeps real chances. Converted to odds, that probability is worth about @1.49; the offered odds are around @1.27 (a 79% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #17 vs #29 (better ranked); 74% career on the surface; model 67% vs market 79% → 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 67%, that outcome happens roughly that percentage of the time, with ~64% out-of-sample accuracy — but being the favorite is not being the winner: roughly 33 out of every 100 times Bejlek 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.
