MELBOURNE, AUSTRALIA (AP) - The mixed doubles draw was a little more star-studded than usual at the Australian Open this year, at least until Andy Roddick’s hamstring injury.

Roddick and Serena Williams had entered the draw to get practice in case they decide to play together at the 2012 London Olympics, but Roddick hurt his leg and withdrew from his second-round singles match on Thursday night.

After seeing Roddick’s injury, Serena tweeted: “Oh no my dubs partner!!!!! :(“

There are a few other intriguing partnerships left in the draw, including the Japanese team of Kimiko Date-Krumm and Kei Nishikori and the Indian duo of Sania Mirza and Mahesh Bhupathi.

With three top men’s doubles players, India is considered a gold-medal threat in the mixed competition. The only question is who will play with Mirza in London.

Though representing different nations, former No. 1 Jelena Jankovic of Serbia is also partnering with Australian teen sensation Bernard Tomic.

Two players that definitely won’t be playing together in London are Roger Federer and Martina Hingis. Federer asked Hingis last year about teaming up for Switzerland, but Hingis declined _ a decision she confirmed Thursday at Melbourne Park.

“We talked at the end of the season,” Hingis told The Associated Press. “I haven’t played for four years. He has to concentrate on singles and (men’s) doubles and I think it’s better that way.”

THEM’S THE BREAKS: Milos Raonic’s perfect serving start to the year has finally been broken.

The big-serving Canadian began the season by winning all 48 of his service games in four matches at Chennai, India _ the first player to win a title without dropping serve since Roger Federer did it in Halle in 2008. He served 76 aces and saved all 14 break points he faced.

Raonic also was perfect on serve in his first-round match at Melbourne Park. However, on Thursday, the streak ended when Germany’s Philipp Petzschner broke him twice in the second round. Raonic at least came away with the win, 6-4, 5-7, 6-2, 7-5.

The 21-year-old later acknowledged he was a little tight during the match.

“It’s always tough to close out a match. Especially for me a big part of closing out matches is my serve. I don’t think in the first game I put in any first serves,” Raonic said.

Raonic has still won 79 of 81 service games to start the season, for an impressive 97.5 percent.
