BREAKDOWN · MODEL ANALYSIS

The model makes E. Rybakina the favorite with a 93% win probability, against Y. Starodubtseva's 7% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.07; the offered odds are around @1.08 (a 93% implied), virtually the same as what the market prices in.

Several factors explain the number: #2 vs #58 (better ranked); 0-1 against; 73% career on the surface; 9/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 93%, 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 7 out of every 100 times Starodubtseva 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 (0-1). This is informational analysis, not a betting recommendation. 18+ · play responsibly.
