BREAKDOWN · MODEL ANALYSIS

The model makes E. Rybakina the favorite with a 51% win probability, against C. Gauff's 49% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.97; the offered odds are around @2.14 (a 47% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #2 vs #4 (better ranked); 5/10 in recent matches; 0-1 against; 73% career on the surface.

Read it with perspective. Our probability is calibrated — when the model says 51%, 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 49 out of every 100 times Gauff 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: Returning from a long layoff (39d) — possible rustiness; Unfavorable head-to-head record (0-1). This is informational analysis, not a betting recommendation. 18+ · play responsibly.
