New York and fashion go hand in hand, and tennis outfits are no exception, especially when we have a high-profile event such as the US Open. So let's see what the manufacturers of tennis clothes prepared for our WTA stars and there is no better way to start than with American Bethanie Mattek Sands who integrated patriotism in her attire.

Don't you love the American-flag tube socks and the accompanying red shoes? Bethanie looks awesome in her Under Armour outfit with accessories that perfectly match the US Open occasion.

Bethanie is known for her experiments with fashion and her most recent took place before and during Wimbledon, when she incorporated tennis balls in her player party and on-court outfits.

Venus Williams shocked with her EleVen US Open dress as much as she did with her subsequent abrupt withdrawal due to a long-undiagnosed syndrome.

Top seed Caroline Wozniacki and Stella McCartney absolutely failed to inspire with a white dress much more suitable for Wimbledon. Why not use colors for the US Open when you can?

Top seed Caroline Wozniacki is feeling good about her current game and eased into the fourth round of the US Open with a 6-2 6-4 victory over American Vania King.

In the first round against Nuria Llagostera Vives Wozniacki lost just four games, in the second against Arantxa Rus just two and against the 103rd-ranked King six games. As is usually the case with Wozniacki's matches, she hit less winners than her opponent – 14 to King's 24, and even dropped serve three times in windy conditions, but King made many unforced errors and Wozniacki advanced while bigger favorite Maria Sharapova crashed out in the third round.

King said she would have reconsidered playing both doubles and mixed doubles if she had known she would reach the third round in singles.

Now that we've seen the kiss and read Rory McIlroy's statement that we can call Caroline Wozniacki his girlfriend, Caroline revealed the things she enjoys in the relationship with her golfer boyfriend – they are both professional athletes and each of them has something the other one is yet to achieve. The slamless Wozniacki would like to match the 22-year-old Rory's US Open title.

I'm definitely trying to keep up. He has something I'm looking for and I have something he's looking for. He wants to be number one, so it's good to have something on each other.

The 21-year-old Wozniacki, who has been on top of the WTA rankings for 46 weeks, was more keen to answer questions about her love life than about her status of a No.1 without a Grand Slam title.

I think we should move on. Ask me about something else, something more interesting.

Golfer Rory McIlroy confirmed his relationship with Caroline Wozniacki in a press conference and planted her a kiss on the lips in front of cameras and a Yale University football team on Friday night.

Last month's rumors about the two dating surfaced when a tennis fan spotted them in London and shared photos on Facebook. Later McIlroy was attending Wozniacki's matches as a spectator, but their relationship wasn't publicly announced. As DeShawn Besabella reports, Rory confirmed relationship with Caroline in a press conference mostly concerning the state of his injuries sustained at a recent tournament. He told the press that they could refer to Caroline his girlfriend. Caroline still hasn't revealed anything officially, but the public kiss should be considered enough.

As you know, the photos of Rory and Caroline with the football team were revealed before, but this photo of the kiss is a new addition, I saw it only today.

The world No.1 Wozniacki won her fourth successive New Haven Open title over the weekend and is top seed at the US Open.

Professional tennis instructor Florian Meier (OnlineTennisInstruction.com) is back reviewing the favorites for the 2011 US Open (his previous guest post on Women's Tennis Blog was an analysis of Sabine Lisicki's game). Even though world No.1 Caroline Wozniacki won the New Haven Open this weekend, the Dane is not high on Florian's list of favorites. Leaders are Serena Williams and Maria Sharapova. Enjoy Florian's introduction to the US Open!

The US Open starts on Monday and it looks like Serena Williams and Maria Sharapova have the best chances for the title. Let’s quickly review the recent action on the women’s tour and then look at the upcoming US Open, which is certainly one of the most exciting tournaments of the year.

The US Open 2011

The US Open Series

Over the last 8 weeks the US Open Series was played out and Serena Williams ended up in first place in the US Open Series rankings. In case she wins the US Open tournament she would receive a $1 million dollar bonus on top of the regular prize money.

Serena is back to top form and did not lose a match in the US Open Series until pulling out of the second round in Cincinnati to rest a troublesome right big toe. She won the tournament in Stanford and the week after she won the Premier-level event in Toronto.

US Open Preview

Looking at the upcoming tournament there is no doubt to me that Serena is the favourite to win the US Open.

Since she won the US Open Series, Serena can now compete for the biggest paycheck in tennis history. If she wins the US Open she will collect $2.8 million dollars. She would get $1.8 million for winning the US Open, and a $1 million dollar bonus for winning both the US Open Series and the US Open. I believe this provides some extra motivation for Serena, especially since she hadn’t played for almost a year.

The other player next to Serena that I see with good chances to win the title is Maria Sharapova.

Sharapova has improved consistently over the last few months. I think she has been working really hard in order to put herself in position to contend for another major. She did well in the US Open Series, winning the Premiere-level event in Cincinnati and she also has the belief and the experience that are usually necessary to win a Grand Slam tournament. For her a lot depends on whether she gets her serve going or not. Read more »

Caroline Wozniacki joined Venus Williams as a player who has won four successive titles at New Haven and became only the tenth woman in the Open Era to win a WTA event four times in a row. After a bye in the first round, Wozniacki defeated Polona Hercog, Christina McHale, Francesca Schiavone, and finally qualifier Petra Cetkovska 6-4 6-1.

After an alarming start of the US Open Series with two losses of two matches played, and a lot of talk about her rumored boyfriend, professional golfer Rory McIlory, the top-ranked Wozniacki improved her hopes for the US Open with a title run at the New Haven Open at Yale. The Dane is now 17-0 at the tournament.

Czech world No.40 Cetkovska had won seven matches with the qualifying rounds, and eliminated big names such as Agnieszka Radwanska, Marion Bartoli and Li Na from the main draw. The 26-year-old is yet to win a WTA title.

Rory was in the stands watching the final and above you can see a photo of him and Caroline with the Yale University football team on Friday.

Three-time defending champion Caroline Wozniacki will play qualifier Petra Cetkovska in the final of the New Haven Open.

The top-seeded Wozniacki was a break down for the most part of the first set of the semifinal against Francesca Schiavone, and it was the third-seeded Schiavone who had 24 winners to 18 errors, compared to Wozniacki's 3 winners and 10 errors. Still, the Dane won at rigth moments and in the tiebreak took the first set. Through the second set she went more comfortably and advanced to the final with a 7-6(2) 6-3 win.

Cetkovska battled to a thrilling 6-2 5-7 7-6(9) victory over second seed Li Na to reach her first WTA final, and nothing less than at a Premier-level tournament. At 5-4 in the third set Cetkovska served for the match, gave Li three break opportunities at 0-40, then saved all the three, but double-faulted on match point. In the tiebreak Li saved two match points before losing one of her own at 8-7. Cetkovska closed out on her fifth match point. Read more »

World No.1 Caroline Wozniacki avenged her last week's Cincinnati loss to Christina McHale with a 7-5 6-3 over the American in the quarterfinals of the New Haven Open where the Dane is now on a 15-0 winning streak including three straight titles. If Wozniacki manages to win four successive titles at a WTA event, she will be the tenth player in the Open Era to do so, and first since Venus Williams' reign in New Haven from 1999 to 2002.

At the tournament where Caroline Wozniacki is aiming for her fourth straight title the Dane rebounded from her US Open lead-up crisis by a convincing 6-3 6-0 victory over Slovenian Polona Hercog. At the last tournament before the New York Grand Slam, Wozniacki finally won a match, while at the preceding events of Toronto and Cincinnati the world No.1, who will be top seed at the US Open, suffered opening round losses.

To make things more interesting, Wozniacki's opponent in the quarterfinal of the New Haven Open will be home favorite Christina McHale, who upset Wozniacki 6-4 7-5 last week at the Western & Southern Open in Cincinnati. Wildcard McHale has already made news this week, having beaten sixth seed Svetlana Kuznetsova in the first round and then rolling past Carla Suarez Navarro in the second.

Additional info: Adidas yesterday sent me this official photo of Wozniacki's US Open dress. So, it will definitely be the white version of the dress, and not the light yellow dress. Also, they sent me the behind-the-scenes video of Wozniacki's photo shoot for Stella McCartney Fall/Winter 2011.

Caroline Wozniacki is suffering an obvious slump of form and now we know that the reason is most probably that she is no longer being coached by her father, Piotr. He is not her main coach any more, but he shows up as a supplementary coach when needed. In an interview for a Danish media outlet Ekstra Bladet, Piotr didn't want to reveal the name of Caroline's new head coach.

The father-daughter cooperation ended after Wimbledon. The reason behind it could be that Caroline is trying to change her overly defensive style of play and add more aggression. Of course, her father will stay by her side, it's just that he will be less present as a coach.

Fellow tennis blogger DeShawn Besabella featured a Google translation of the interview with Piotr Wozniacki from ekstrabladet.dk. This piece of news is still fresh, we will surely get more details soon. (photo by our reader Tony)
