BREAKDOWN · MODEL ANALYSIS

The model makes I. Swiatek the favorite with a 72% win probability, against E. Mertens's 28% — a solid favorite, though Mertens keeps real chances. Converted to odds, that probability is worth about @1.38; the offered odds are around @1.22 (a 82% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #9 vs #19 (better ranked); 2-0 in favor; 79% career on the surface; model 72% vs market 82% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 72%, 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 28 out of every 100 times Mertens 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.
