BREAKDOWN · MODEL ANALYSIS

The model makes J. Brooksby the favorite with a 53% win probability, against L. Sonego's 47% — a tight match, without a wide margin. Converted to odds, that probability is worth about @1.89; the offered odds are around @1.78 (a 56% implied), slightly below the market, so the model is a touch more cautious.

Several factors explain the number: #77 vs #86 (better ranked); 5/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 53%, 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 47 out of every 100 times Sonego 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.
