Roger Federer breezes through first round against Leonardo Mayer at US Open
Quit list reaches record nine as heat and humidity claim more victims

Five-time champion Roger Federer breezed through sweltering conditions at the US Open on Tuesday as 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.
I feel good now. I actually wasn’t so confident yesterday
The 34-year-old Swiss, bidding to become the oldest champion in New York in 45 years, fired 12 aces, 29 winners and broke serve six times.
The 17-time Grand Slam champion goes on to face either Marcos Baghdatis or Steve Darcis.
“I feel good now. I actually wasn’t so confident yesterday. I just felt like maybe it could be one of those matches I just couldn’t see coming,” said Federer, who had saved five match points to beat Mayer in their only other meeting in Shanghai last year.
