BREAKDOWN · MODEL ANALYSIS

The model makes S. Tsitsipas the favorite with a 61% win probability, against R. Hijikata's 39% — a solid favorite, though Hijikata keeps real chances. Converted to odds, that probability is worth about @1.64; the offered odds are around @1.30 (a 77% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #44 vs #82 (better ranked); 2-0 in favor; 62% career on the surface; model 61% vs market 77% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 61%, that outcome happens roughly that percentage of the time, with ~65% out-of-sample accuracy — but being the favorite is not being the winner: roughly 39 out of every 100 times Hijikata 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.
