BREAKDOWN · MODEL ANALYSIS

The model makes A. Sabalenka the favorite with a 82% win probability, against S. Bejlek's 18% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.22; the offered odds are around @1.12 (a 89% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #1 vs #35 (better ranked); 7/10 in recent matches; 76% career on the surface; model 82% vs market 89% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 82%, 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 18 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. This is informational analysis, not a betting recommendation. 18+ · play responsibly.
