Federer hammers del Potro to advance

Roger Federer, playing in his final event before the US Open, surged into the third round of the ATP and WTA hardcourt tournament Tuesday by beating Juan Martin del Potro in straight sets.

The Swiss star, who turned 30 earlier this month, cruised past del Potro 6-3, 7-5 for his first win over the Argentine in their last three matches which included the 2009 US Open final.

Federer had won their first six meetings, dating back to Wimbledon in 2007.

"I played some tough matches against him in the past and obviously the US Open final sticks out the most," Federer said. "I told him at the net that it was good to see him back."

Federer hammered 12 aces and won 83 percent of his first-serve points in the 92 minute match on centre court. AFP
