BREAKDOWN · MODEL ANALYSIS

The model makes A. Korneeva the favorite with a 54% win probability, against T. Preston's 46% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.87; the offered odds are around @1.34 (a 75% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #81 vs #94 (better ranked); performs +6% above baseline (56% career on the surface); model 54% vs market 75% → the model sees it as less likely than the odds; 7/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 54%, 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 46 out of every 100 times Preston 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.
