Zverev A. vs Halys Q.

Published reasoning

Estimated probability: 84%. Zverev took a set in all four comparable completed hard-court matches this month, beating Wu, Shang and Norrie 2-0 and losing 1-2 to Djokovic. His September US Open wins over Shelton and Khachanov support his level but are excluded from the best-of-three sample. Main risk: Halys has sets in all eight comparable recent hard matches, just beat Blockx and took Zverev to five sets on September 4. Rankings 2 versus 48 and model 84% favor Zverev; the smaller sample keeps this a set selection.
