BREAKDOWN · MODEL ANALYSIS

The model makes C. Gauff the favorite with a 90% win probability, against Z. Sonmez's 10% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.11; the offered odds are around @1.05 (a 95% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #4 vs #53 (better ranked); 71% career on the surface; model 90% vs market 95% → the model sees it as less likely than the odds; 9/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 90%, 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 10 out of every 100 times Sonmez 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.
