Stan Wawrinka vs Matteo Berrettini: AI Prediction | Games, Spread, Aces & Double Faults

The model's edge for Berrettini comes mainly from overall strength and age — reflected in his higher Elo (1723.68) and superior ranking (No. 51 versus Wawrinka's 109). Those factors together contribute the largest shares of the prediction swing toward Berrettini. Wawrinka narrows the gap with pockets of advantage: recent form and low tournament fatigue slightly help him, and the model also gives a modest boost for his serve-and-return profile. Looking at the numbers: Berrettini carries the higher form index (41.41 vs 35.31) and a stronger surface strength index on grass (8.80 vs 7.80). Wawrinka’s mean return index (92.80) is notably better than Berrettini’s (84.94) — a meaningful difference that suggests he can pressure Berrettini’s service games. Serve indices are both elite (95.61 for Wawrinka, 96.94 for Berrettini), but the gap is small. Both players arrive with zero accumulated fatigue from the tournament.
