BREAKDOWN · MODEL ANALYSIS

The model makes E. Rybakina the favorite with a 52% win probability, against I. Swiatek's 48% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.94; the offered odds are around @2.50 (a 40% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #2 vs #5 (better ranked); 7/10 in recent matches; 5-6 against; 73% career on the surface.

Read it with perspective. Our probability is calibrated — when the model says 52%, 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 48 out of every 100 times Swiatek 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. Watch out for: Unfavorable head-to-head record (5-6).
