The absence of injured top players Jannik Sinner and Carlos Alcaraz has opened the Cincinnati Open field, leaving Alexander Zverev as the top seed and consensus leader at 27.5% implied probability. Zverev brings seven Masters 1000 titles, including strong hard-court results, plus recent French Open success, though an early Canadian Open exit raises questions about current form. Taylor Fritz sits second at 13.5% after his Washington title, with a favorable bottom-half draw, while emerging talents like Rafael Jodar and established names including Novak Djokovic, Felix Auger-Aliassime, and Jakub Mensik add depth. The spread across multiple contenders reflects a wide-open draw, variable recent results, and the potential for upsets in best-of-three matches on hard courts.
