WIMBLEDON, England (AP) Still waiting for her first Grand Slam title, top-seeded Caroline Wozniacki is used to answering questions about whether she deserves her No. 1 ranking.

On Friday, after beating Virginie Razzano of France 6-1, 6-3 in the second round at Wimbledon, the Dane faced a new line of inquiry: Did she share Serena Williams' sense of being snubbed by organizers for being put on Court 2?

Wozniacki is the third woman in the last three years to reach the top ranking without having won a major title - and she has been getting grilled about that fact for months.

I think I deserve to be where I am. I won so many tournaments already, five this year,'' said Wozniacki, who lost in the third round at the French Open.I'm playing good tennis. I'm young. I'm competitive. My time will come.''

Even if she fails to win at Wimbledon, the Dane is guaranteed to stay as No. 1 until at least Aug. 1.

Against Razzano, Wozniacki finished the match with only one unforced error.

Some were left wondering if the All England Club made an error in scheduling her match on Court 2 instead of on Centre Court or Court 1 - a complaint lodged by four-time Wimbledon champion Williams after she played on Court 2 Thursday.

Obviously I think I deserve to play on one of the bigger courts. Obviously, everyone wants to play in there,'' said Wozniacki, the 2006 Wimbledon junior champion who has yet to even reach the quarterfinals in the main draw.It's up to the tournament to decide where we're going to play. I just go out there and I try to win. I'm a competitor, so it really doesn't matter.''

Williams criticized officials for sticking her and older sister Venus, a five-time champion, on Court 2 for one match each this week. Tournament spokesman Johnny Perkins said there was no intentional snub, but Andy Roddick said it was a bit of a shock to see Serena placed in the smaller stadium.

If it wasn't a little surprising, we wouldn't be talking about it,'' said Roddick, who lost to Feliciano Lopez of Spain 7-6 (2), 7-6 (2), 6-4 in the third round Friday.So there's got to be something to it. ... We were all pretty surprised about it, I've got to be honest, when we saw it.''

Venus played, and won, on Court 1 on Friday. She was asked about the Court 2 issue after beating Maria Jose Martinez Sanchez of Spain 6-0, 6-2 to reach the fourth round.

Rafael Nadal, Roger Federer, Novak Djokovic and Andy Murray have played all of their matches this week in the two principal stadiums, and Venus was asked by a reporter about a ``perception that it's the women'' who get short shrift by being sent to Court 2.

Well, I think you made your own observations already,'' Venus responded.I think go ahead and write what you feel is the truth and what's right.''

She made sure to note that she doesn't have any problems with Court 2 itself.

Court 2 is a solid court,'' Venus said.I mean, like I said before, I'm grateful that it didn't rain when I played on Court 2. When I played on Centre, I was grateful to be able to play that match when it rained and I was under the roof. So it's all worked out pretty well for me so far.''

Wozniacki fared well on the smaller court, too. She had two aces and watched her opponent make 14 unforced errors. But she saw also something not often seen during a Grand Slam tennis match - a ball seemingly falling from the sky.

Leading 5-2 in the second set, Wozniacki held her second match point when Razzano was about to hit a winner. But the Dane held up her hand as a stray ball landed on Court 2 - perhaps from a neighboring court - and disrupted her concentration.

The point was replayed and Razzano won it again, eventually holding serve.

Well, I think that ball came from the other court. I saw it coming,'' said Wozniacki, who held serve in the next game to win the match.I saw it moving into the court. Then I asked for replaying the point.''

ALL A-TWITTER: Andy Murray's mother is all a-Twitter about Feliciano Lopez. Gave him a new nickname, even.

Judy Murray has made no secret of her admiration of the Spaniard and tweets regularly about the man she calls ``Deliciano,'' often exchanging comments on the social media site with Lopez's mixed doubles partner, Andrea Petkovic.

After the long-haired Lopez's win over Andy Roddick at Wimbledon on Friday, Judy tweeted: ``Oooooooooh Deliciano........looking good out there. As always.''

Lopez, also known to his fans as F-Lo, caught on to his new moniker a few days ago.

She's so funny,'' Lopez said of Murray's mom.It's just something that everybody knows now because somebody post it on Twitter. I have to like it. It's kind of funny. I mean, it's OK.''

And what about Judy's son?

I think it's about time she stopped with that nonsense. Makes me want to throw up,'' Andy said, tongue planted firmly in cheek.It's disgusting.''

Judy Murray might have a problem when the quarterfinals roll at Wimbledon this year: Lopez could play her son.

I hope,'' Andy said,she'll still be supporting me.''

TOMIC TONIC: The youngest player in the men's singles tournament is about to become Australia's new No. 1.

Eighteen-year-old qualifier Bernard Tomic came from two sets down for the first time in his career to beat Igor Andreev 4-6, 5-7, 6-3, 6-4, 6-1 Friday and reach the third round at Wimbledon.

Tomic's ranking is set to rise from 158th to around 130th, overtaking two-time Grand Slam champion Lleyton Hewitt.

``It's a good feeling,'' the teenager said.

Tomic's win was a welcome tonic for Australia's tennis fans, too: If he hadn't won, Australia would have been without a man in the third round of Wimbledon for the first time in the Open era, which began in 1968.

Qualifier Marinko Matosevic lost in the first round, while Hewitt went out in the second round after a five-set match with fifth-seeded Robin Soderling, Tomic's opponent Saturday.

He can hit you off the court, as he's done the last few years,'' Tomic said.He's beaten a lot guys very easily. He can just hit winners and push me off the court. So, yeah, I've got to serve well tomorrow. And if I serve well, I think my baseline game will improve.''

Tomic, who was born in Stuttgart, Germany, and moved to Australia with his family when he was 3, also reached the third round at the Australian Open in January, beating Jeremy Chardy and Feliciano Lopez before losing to Rafael Nadal.

He is still coached by his father John, but says he has been taking advice from two-time U.S. Open champion Patrick Rafter, Australia's Davis Cup captain and a two-time Wimbledon finalist.

It's good to get advice from Pat like that. He was a great player,'' Tomic said.He obviously did really well here and he's won Slams. Any advice from a player like that is good.''
