BREAKDOWN · MODEL ANALYSIS

The model makes M. Chwalinska the favorite with a 64% win probability, against D. Yastremska's 36% — a solid favorite, though Yastremska keeps real chances. Converted to odds, that probability is worth about @1.56; the offered odds are around @1.50 (a 67% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #21 vs #111 (better ranked); 6/10 in recent matches; 8 matches in the last 2 weeks; 6d vs opponent's 2d.

Read it with perspective. Our probability is calibrated — when the model says 64%, 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 36 out of every 100 times Yastremska 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: Coming off 4 losses in a row.
