BREAKDOWN · MODEL ANALYSIS

The model makes A. Rublev the favorite with a 64% win probability, against T. Griekspoor's 36% — a solid favorite, though Griekspoor keeps real chances. Converted to odds, that probability is worth about @1.56; the offered odds are around @1.61 (a 62% implied), virtually the same as what the market prices in.

Several factors explain the number: #24 vs #55 (better ranked); 3-1 in favor; 62% career on the surface; 6/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 64%, 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 36 out of every 100 times Griekspoor 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.
