Caroline Wozniacki remained undefeated at the Pilot Pen Tennis at Yale (13-0), winning her third consecutive title at the tournament with a 6-3 3-6 6-3 win over Nadia Petrova in the final. It’s the Dane’s second title of the week, as she won the rain-delayed Rogers Cup final against Vera Zvonareva on Monday.

The top-seeded Wozniacki was leading 6-3 2-0 when Petrova took charge and won the second set of the New Haven final. Then in the third set Wozniacki established a 4-1 lead and although Petrova managed to come closer, to 4-3, Wozniacki played two good games to close out the match.

Wozniacki now heads to the US Open, where she is top seed, with four WTA titles this season, which is more than any other player on the Tour has won. Her first opponent at the US Open will be American wildcard Chelsey Gullickson, who is unranked. (via Sony Ericsson WTA Tour)

This is the third time Caroline Wozniacki is playing at New Haven and she still hasn’t lost a match here, improving to 12-0 with a 1-6 6-3 7-6(5) triumph over Elena Dementieva in this year’s semifinals.

The top-seeded Wozniacki will play eighth seed Nadia Petrova in the final of the Pilot Pen Tennis at Yale. Wozniacki is 2-1 lifetime against Petrova, with both the wins coming this season, at Indian Wells and Charleston. The one encounter Wozniacki lost was two years ago and she had to retire.

Wozniacki is occupying the top spot in the final Olympus US Open Series standings for 2010, meaning that the US Open title would bring her an additional $1 million. Wozniacki was runner-up at last year’s US Open, and this time she’ll be No.1 seed.

Additional info: A couple of days ago Wozniacki said how she would like to take a class or two at Yale, probably online. It would be a nice addition to her life, so that not everything revolves around tennis. She wanted to carry that idea out this year, but her professional obligations prevented her from doing so.

Top seed at the Pilot Pen Tennis at Yale, Caroline Wozniacki, didn’t even have to play her quarterfinal match as Flavia Pennetta withdrew with a right foot injury. The Dane’s opponent in the semifinals will be No.4 seed Elena Dementieva who fought for exactly three hours to defeat No.6 seed Marion Bartoli 6-3 3-6 6-2.

Second seed Samantha Stosur was quickly beaten by seed No.7 Nadia Petrova, 6-2 6-1 in just 53 minutes. Stosur started the match by breaking Petrova’s serve, but from then on Petrova lost just three points in her other six service games and broke Stosur five times. Petrova now has 4-0 head-to-head record against Stosur, and all her wins came in straight sets (actually, she has never lost more than three games in any of those sets).

Maria Kirilenko will be Petrova’s opponent in the semifinals. Kirilenko advanced with a 6-3 6-3 win over Dinara Safina. After the match Kirilenko commented on Safina’s weakened game: "Before she was more aggressive, but now she's making longer points, and it's not hurting you as much."

World No.2 Caroline Wozniacki was supposed to play her Rogers Cup semifinal against Svetlana Kuznetsova on Saturday but persistent rain in Montreal delayed the most part of the match all the way to Monday, which forced the final to be played shortly after.

The 20-year-old cruised to a 6-2 6-3 victory over Kuznetsova in the semifinals without dropping serve and only hours later played for the title against Vera Zvonareva, who reached the final after Victoria Azarenka retired due to a blister on her left foot at 7-6(6) 1-0 down.

Wozniacki disposed of two of the highest-ranked Russian players in one day as she followed the win over world No.12 Kuznetsova with a convincing 6-3 6-2 win over eighth-ranked Zvonareva.

Wozniacki has collected her ninth Sony Ericsson WTA Tour singles title and third of the year (after Ponte Vedra Beach and Copenhagen). She and Kim Clijsters are now the only two players that have won three titles this season. The two faced each other in the last year's final of the US Open, and this time they will be the Top 2 seeds at the Grand Slam. (photo via Rogers Cup)

Caroline Wozniacki has been wearing nice adidas by Stella McCartney dresses but you can’t distinguish one from another and a while ago she promised something exclusive for the 2010 US Open. Browsing the Internet I came across the dress the Dane is supposed to wear at the final Grand Slam of the year.

At first glance the outfit looks plain ugly, in my opinion at least. It reminds me of a bad choice worn to a club. But, I’m a huge believer in Stella McCartney’s taste, and I’m sure the dress will look good on Caroline and in action.

What do you think?

And yes, there is also the white version of the dress, as well as a green and gray one which is the most beautiful. The official name of the piece is Stella McCartney Tennis Performance Dress.

Update: as our reader Cara says, the what I called green and gray dress is actually the black night dress with the new Yellow Stella Sports Bra. Haha it looked green and gray to me.
