BREAKDOWN · MODEL ANALYSIS

The model makes S. Tsitsipas the favorite with a 55% win probability, against L. Darderi's 45% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.82; the offered odds are around @1.41 (a 71% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #43 vs #21; 1-0 in favor; 62% career on the surface; model 55% vs market 71% → the model sees it as less likely than the odds.

Read it with perspective. Our probability is calibrated — when the model says 55%, 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 45 out of every 100 times Darderi 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.
