- Five-time champion Roger Federer breezed through sweltering conditions at the US Open but the crushing heat and humidity took the number of first-round retirements to a record nine. Second-seeded Federer had little trouble in seeing off Argentina's world number 34 Leonardo Mayer 6-1, 6-2, 6-2 in just 77 minutes on Arthur Ashe Stadium. However, the day's drama was being served-up on Court Five where Australia's Thanasi Kokkinakis retired on one leg after cramping badly in the fifth set against French 12th seed Richard Gasquet after being advised by the umpire that he was putting his health at risk if he continued. He was the eighth man to retire from the first round, a record for the US Open before Kazakhstan's Aleksandr Nedovyesov quickly became the ninth.
