!Returning from a long layoff (32d) — possible rustiness
The model makes J. Ostapenko the favorite with a 67% win probability, against S. Zhang's 33% — a solid favorite, though Zhang keeps real chances. Converted to odds, that probability is worth about @1.49; the offered odds are around @1.43 (a 70% implied), slightly below the market, so the model is a touch more cautious.
Several factors explain the number: #31 vs #64 (better ranked); 7/10 in recent matches.
Read it with perspective. Our probability is calibrated — when the model says 67%, 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 33 out of every 100 times Zhang 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 (32d) — possible rustiness.
