BREAKDOWN · MODEL ANALYSIS

The model makes P. Badosa the favorite with a 77% win probability, against D. Semenistaja's 23% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.31; the offered odds are around @1.14 (a 88% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #70 vs #120 (better ranked); 70% career on the surface; model 77% vs market 88% → the model sees it as less likely than the odds; 8/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 77%, 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 23 out of every 100 times Semenistaja 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.
