Jiri Lehecka vs Jannik Sinner: AI Prediction | Games, Spread, Aces & Double Faults

On paper the contrasts are stark: Sinner carries a higher form index (87.8 vs 75.1) and a much stronger Elo rating (2472.0 vs 1785.9), while both players are battle-tested this week with similar cumulative minutes (Lehecka 408, Sinner 426). Sinner’s surface strength (78.4) outpaces Lehecka’s (62.1), and his mean serve index (96.9) is markedly superior to Lehecka’s (82.3) — a difference greater than 5 points that will matter on serve. The mean return gap is even larger (89.3 vs 42.2), indicating Sinner’s return game is a pronounced advantage on this medium-paced hard court. Form at Miami reinforces those metrics. Lehecka has been consistent, three straight wins including a tough 145-minute victory over Taylor Fritz and a 75-minute quarterfinal win over Arthur Fils, demonstrating resilience but accumulating court time. Sinner has advanced without dropping a set in his last three matches, beating quality opponents in relatively efficient matches (71–113 minutes), which aligns with his higher form index and suggests superior control in key moments.
