Quentin Halys vs Alexander Zverev: AI Prediction | Games, Spread, Aces & Double Faults

The numbers sharply favor Zverev. He arrives ranked No. 4 with an Elo of 2044.5, a strong surface strength index of 84.39 and a form index of 80.57. Halys is ranked 111, carries a 1697.0 Elo, a surface index of 51.29 and a form index of 74.38. Fatigue is a factor: Halys has logged 314 minutes in Miami compared with Zverev’s 226, which could blunt Halys’s legs late in rallies. The serving and returning gaps are notable—Zverev’s mean serve index (97.84) is over 8 points higher than Halys’s (89.48), and his mean return index (89.56) dwarfs Halys’s 37.58. Both differences exceed five points and point to Zverev controlling both service games and breaks. Recent form tells a consistent story. Halys has won three straight matches in Miami, including straight-sets wins over Alejandro Davidovich Fokina and Kamil Majchrzak, but those wins came with heavy minutes (110 and 78 minutes) and a cumulative 314-minute workload. Zverev has also won his last two Miami matches, including a marathon 157-minute victory over Marin Cilic; he did suffer a loss at Indian Wells to Jannik Sinner earlier, but his recent results and higher-class opponents underline his readiness.
