BREAKDOWN · MODEL ANALYSIS

The model makes Frances Tiafoe the favorite with a 85% win probability, against Kei Nishikori's 15% — a conviction read: the model sees the match clearly leaning one way. Converted to odds, that probability is worth about @1.17; the offered odds are around @1.23 (a 81% implied), slightly above the market, so the model is a touch more optimistic.

Several factors explain the number: #8 vs #436 (better ranked); 0-1 against; 8/10 in recent matches.

Read it with perspective. Our probability is calibrated — when the model says 85%, 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 15 out of every 100 times Nishikori 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: Unfavorable head-to-head record (0-1). This is informational analysis, not a betting recommendation. 18+ · play responsibly.
