The model makes Alexander Zverev the favorite with a 87% win probability, against Botic van de Zandschulp's 13% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.15; the offered odds are around @1.13 (a 88% implied), virtually the same as what the market prices in.
Several factors explain the number: #2 vs #70 (better ranked); 7/10 in recent matches; 69% career on the surface; 21d vs opponent's 13d.
Read it with perspective. Our probability is calibrated — when the model says 87%, 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 13 out of every 100 times Zandschulp 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 (21d) — possible rustiness.
