Venus storms through to Serena showdown

NEW YORK (Reuters) - Seventh seed Venus Williams set up a quarter-final against her sister Serena at the U.S. Open after she eased past Polish ninth seed Agnieszka Radwanska 6-1 6-3 on Monday.

The Wimbledon champion roared through the first set and staved off a mini-fightback by Radwanska in the second to reach the quarter-finals for the ninth time.

Coming forward at every opportunity, Williams overpowered a hapless Radwanska early on, smashing 14 winners on her way to the first set.

Radwanska lifted her game to get a foothold in the second set, recovering an early break to level at 3-3, but Williams saved a break point in the eighth game and then broke again for victory.

"She raised the level of her game, started trying to attack more, move in, playing more aggressive shots; that was smart of her," Williams said of Radwanksa's second-set showing.

"She had some opportunities, but fortunately I was able to get them right back."

Fourth seed Serena Williams beat unseeded Severine Bremond of France 6-2 6-2.
