After all the Dane, thanks to her relationship with Rory McIlroy, spends most of her time in headlines which have little to do with hitting a ball with a racket.
A lack of success on the court - the 23-year-old has plummeted from world No.1 to No.8 in the course of the last 18 months and not added to her career tally of 20 titles this year - has certainly ensured her love life is far more interesting than her displays which, on the whole, have been highly inconsistent and dispiriting.
McIlroy, who watched his girlfriend eventually make light work of China's Ying-Ying Duan yesterday, was moved to rubbish yet more recent reports that the pair were to split.
In a show of solidarity, and to ostensibly keep the whispers at bay, the pair were pictured together in the hours before Wozniacki went out on to Arthur Ashe court and then dispensed with Duan in one hour and 41 minutes. "I love my life. I love what I am doing and I wake up wanting to improve, " she said. "The highs come with the lows but ask any top level sportsperson the same question and they will give you the same response.
"Myself and Rory both love what we do but we don't always talk about our own careers. It's not something we talk about purposely. It's kind of different, when he is closing in on the final rounds, it's hard to know how to advise him."
With Serena Williams looking as ominous as ever, the Dane will really have to pull something special out of the bag to win her maiden slam. Duan, the unseeded 24-year-old in her first grand slam event, had a 5-2 lead in the second but nerves and inexperience ensured dozens of unforced errors let Wozniacki back in.
Grigor Dimitrov, the latest squeeze of Maria Sharapova, is another player for whom there is as much interest off the court as there is on it. The Bulgarian has long been trumpeted as one of the new breed - alongside such as the Canadian Milos Raonic, who made a winning start yesterday beating Thomas Fabbiano in straight sets - to make real inroads into threatening the likes of Andy Murray, Novak Djokovic et al at the top of world tennis.
His performances in the slams this year, though, suggest otherwise. A first-round exit in Australia has been followed by third- and second-round losses in Paris and at Wimbledon respectively.
Yesterday, his five-set defeat by Joao Sousa, ranked 95 in the world, proved suggestions of his ability to challenge at the very top of the men's game could well be wide of the mark.He has never won a match at Flushing Meadows and, on this evidence, he could be waiting a while to break that particular duck.
Like Dimitrov, the big-serving Jerzy Janowicz is being tipped for a strong future, especially after his impressive run to the last four at Wimbledon. But there won't be a similar run in New York, a shame because his huge hitting style would favour these bouncy courts, mainly thanks to a back problem which resulted in him serving underarm in a vain attempt to stay alive in the match. It was not enough though as the Argentinian qualifier Maximo Gonzalez, ranked 247 in the world, sent the No.14 seed out 6-4, 6-4, 6-2.
Ana Ivanovic, the former world No.1, made a strong start before revealing she was playing with a heavy heart after hearing about the death of a childhood friend back home in Serbia. Vukasin Ziramov, 25, died last week after jumping off a bridge into a river while on an outing with friends in Senta.
"It's been very sad news," Ivanovic, the 13th seed at Flushing Meadows said after her 6-2, 6-0 rout of Anna Tatishvili of Georgia. "It was very hard. It was almost like my relative. I knew him since we were kids."
