World number three Roger Federer extended his unbeaten run in competitive matches to 19 with a victory over Grega Zemlja in Doha earlier today.
The Swiss number one moved into round three of the Qatar Open with relative ease, seeing off his opponent 6-2 6-3.
After the match Federer revealed that he found the windy conditions easier to deal with than previous matches.
"It is important not to get frustrated in the wind, like I maybe did when I was younger," he said. "You become used to it."
Federer will take on Andreas Seppi in round three tomorrow afternoon.
