E. Svitolina vs S. Sierra — prediction

The model makes E. Svitolina the favorite with a 87% win probability, against S. Sierra's 13% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.15; the offered odds are around @1.08 (a 93% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #9 vs #87 (better ranked); 65% career on the surface; model 87% vs market 93% → the model sees it as less likely than the odds; 7/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 87%, 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 13 out of every 100 times Sierra 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.
