!Returning from a long layoff (25d) — possible rustiness
The model makes A. Kalinskaya the favorite with a 55% win probability, against Q. Zheng's 45% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.83; the offered odds are around @2.46 (a 41% implied), slightly above the market, so the model is a touch more optimistic.
Several factors explain the number: #22 vs #54 (better ranked); 1-1 even; 61% career on the surface; model 55% vs market 41% → the model sees it as more likely than the odds.
Read it with perspective. Our probability is calibrated — when the model says 55%, 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 45 out of every 100 times Zheng 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 (25d) — possible rustiness.
