Andy Roddick weathered an early onslaught from Ukrainian Alexandr Dolgopolov before steamrolling him 6-4, 6-1 to book a quarterfinal place at the Brisbane International on Wednesday. The 22-year-old Dolgopolov attacked Roddick's serve to win an early break and go up 4-2. But the American world No. 8 quickly broke back, however, and reeled off 10 of the final 11 games to seal the match in less than an hour.
Roddick rocketed down 15 aces in the match to raise $1,508 in donations for victims of devastating floods in northern Queensland state that have affected 200,000 people.
"It's a very small part what we're doing here. It was Sam Stosur's idea," said the 2003 U.S. Open champion, who joined the Australian women's world No. 6 in pledging $100 per ace.
The second-seeded Roddick defeated Czech Radek Stepanek in the final last year on the way to a quarterfinal appearance at the Australian Open. He will face either Cypriot Marcos Baghdatis or Poland's Lukasz Kubot.
