Williams Sisters, Djokovic Advance at Australian Open

Sisters Serena and Venus Williams both advanced to the third round of the Australian Open, while men’s top seed Novak Djokovic won his second-round match in 84 minutes.

Serena Williams, the top seed in Melbourne and a five-time champion at the season’s first Grand Slam tennis tournament, fought off three set points before winning the last 10 games of the match for a 7-5, 6-0 defeat of Russia’s Vera Zvonareva.

Williams twice lost her serve in the opening set and trailed 5-3 when she faced the set points on her serve. She recovered to win that game and then the 58-minute first set, before capturing the second set in 27 minutes.

“She was aggressive and I was a little too passive,” Williams said of the first set against Zvonareva, who was ranked No. 2 in the world in 2010 when she reached the final at Wimbledon and the U.S. Open but has fallen to No. 203 after a run of injuries and illness.

Venus Williams advanced with a 6-2, 6-3 defeat of fellow American Lauren Davis. Williams, seeded 18th, had four aces and broke Davis’s serve five times in the match.

Also reaching the third round was sixth-seeded Agnieszka Radwanska of Poland, who needed 44 minutes to win 6-0, 6-1 against Sweden’s Johanna Larsson.

Djokovic, from Serbia, won 6-0, 6-1, 6-4 against Russia’s Andrey Kuznetsov and moved on to a match against Japan’s Go Soeda or No. 31 Fernando Verdasco of Spain.

John Isner, at No. 19 the top American men’s seed in the tournament, had 28 aces in a 6-4, 7-6 (7-4), 4-6, 6-4 win against Austria’s Andreas Haider-Maurer.

Joining him in the third round was fifth-seeded Kei Nishikori of Japan, a finalist at last year’s U.S. Open. Nishikori dropped the opening set before winning his match in four sets against Ivan Dodig of Croatia.
