BREAKDOWN · MODEL ANALYSIS

The model makes A. Sabalenka the favorite with a 94% win probability, against R. Zarazua's 6% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.06; the offered odds are around @1.03 (a 97% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #2 vs #94 (better ranked); 1-0 in favor; 76% career on the surface; 8/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 94%, 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 6 out of every 100 times Zarazua 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. This is informational analysis, not a betting recommendation. 18+ · play responsibly.
