Nadal breezes into 3rd round of Australian Open

MELBOURNE, Australia (AP) - Rafael Nadal extended his Grand Slam winning streak to 23 matches with a 6-2, 6-1, 6-1 win over American qualifier Ryan Sweeting to reach the third round of the Australian Open.

The top-ranked Nadal is aiming to be the first man since Rod Laver in 1969 to hold all four Grand Slam titles at the same time.

He's conceded only four games en route to the third round, sealing his win over Sweeting on today with another of his rifling forehands.

After retiring with an injury in the quarterfinals at the last Australian Open, Nadal rebounded to win the French, Wimbledon and U.S. Open.

Nadal hit some shots that Sweeting could barely believe, including an ace to finish the first set and forehand on set point in the second when the Spaniard's curling shot caught the baseline for the winner. Sweeting challenged the call as he walked off, but the call stood."

The only hint of anything other than complete domination for Nadal came in the third set, when Sweeting broke serve in the fifth game and then had game points to bring it back to 4-2 in a game that went to deuce five times. Again, Nadal held on to convert a break and served out in the next game.

"I feel good. Today the serve started to work much better," Nadal said. "Only one (bad) moment, when the sun came in my eyes," Nadal said. "It was a positive victory for me, an important victory."

All the coverage of his "Rafa Slam" had no influence on Nadal's mindset.

"No, for sure, it's not a distraction," he said. "It's the last thing I'm thinking about right now. I'm trying to find my best level."

Kim Clijsters showed why she's fast becoming a hot favorite for the women's title by beating Carla Suarez Navarro 6-1, 6-3.

U.S. Open champion Clijsters opened with a 6-0, 6-0 win over former No. 1-ranked Dinara Safina, but Suarez Navarro was a potentially dangerous second-round matchup.

Joining her in the third round from the bottom half of the draw were No. 10 Shahar Peer, who beat Sorana Cirstea 6-3, 6-2 and No. 22 Flavia Pennetta, who beat Lourdes Dominguez 6-2, 6-2.

Seventh-seeded Jelena Jankovic lost 7-6 (3), 6-3 to China's Peng Shuai, continuing an unimpressive streak of seven losses in eight matches. It was former world No. 1 Jankovic's worst result at a major since the 2009 U.S. Open.

While Clijsters has advanced with ease, Venus Williams has had a challenging time.

Williams injured a muscle between her stomach and groin Wednesday as she twisted for a volley. She needed a medical timeout after losing the first set. She was on the verge of tears, and apparently elimination. But she refused to stop playing, something she has never done in a Grand Slam match.

The seven-time Grand Slam winner rallied to take the next two sets and defeat Sandra Zahlavova of the Czech Republic 6-7 (6), 6-0, 6-4.

Roger Federer faced a more familiar problem - Gilles Simon. He's one of only three men on tour with a winning record against the Swiss great. Federer raced to a two-set lead in a second-round night match, and seemed in the clear. He had never while lost so far ahead in a Grand Slam tournament.

Then Simon, who beat Federer twice in 2008 on hard courts in their only two previous encounters, started to take more risks, moving the 16-time Grand Slam champion out of his comfort zone. But Federer persevered, finishing off a 6-2, 6-3, 4-6, 4-6, 6-3 victory on his fifth match point.

"I'm happy I survived a scare like today," he said.

Nadal, one of the other men who have a winning record against 16-time Grand Slam winner Federer, watched the match on TV.

"It was fantastic tennis. Simon had an amazing comeback. In the fifth set, Federer played unbelievably well in important moments."
