The model makes Alexander Zverev the favorite with a 88% win probability, against Tallon Griekspoor's 12% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.14; the offered odds are around @1.12 (a 89% implied), virtually the same as what the market prices in.
Several factors explain the number: #3 vs #67 (better ranked); 8/10 in recent matches; 7-2 in favor; 70% career on the surface.
Read it with perspective. Our probability is calibrated — when the model says 88%, 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 12 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. Watch out for: Returning from a long layoff (24d) — possible rustiness.
