BREAKDOWN · MODEL ANALYSIS

The model makes M. Chwalinska the favorite with a 69% win probability, against R. Sramkova's 31% — a solid favorite, though Sramkova keeps real chances. Converted to odds, that probability is worth about @1.46; the offered odds are around @1.52 (a 66% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #25 vs #146 (better ranked); 4/10 in recent matches; 2 wins in a row.

Read it with perspective. Our probability is calibrated — when the model says 69%, 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 31 out of every 100 times Sramkova 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 (21d) — possible rustiness.
