BREAKDOWN · MODEL ANALYSIS

The model makes M. Keys the favorite with a 55% win probability, against S. Bejlek's 45% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.81; the offered odds are around @1.48 (a 68% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #24 vs #35 (better ranked); 62% career on the surface; model 55% vs market 68% → the model sees it as less likely than the odds; 6/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 55%, 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 45 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.
