Stomach virus runs through Madrid Open field as tennis stars try to navigate puking and pollen

A stomach virus and heavy pollen have severely disrupted the 2025 Madrid Open, forcing multiple high-profile withdrawals and retirements. Australian Open champion Madison Keys withdrew due to illness on April 24, while seven-time Grand Slam champion Iga Świątek retired mid-match against Ann Li citing a virus. Other players including Marin Čilić and Liudmila Samsonova also gave walkovers, compounding an already disrupted tournament field one month before the French Open.
