Wozniacki selling underwear, blowing up at umpires

Former No. 1 Caroline Wozniacki announced that she was partnering with a Danish clothier to release a line of lifestyle and leisure underwear. Her "This is Me" line will be released worldwide in September. It includes low hipsters, g-strings and bras. The undergarments were designed with "Caroline's personal input to reflect her individual style and desired level of comfort."

"A feminine lifestyle/leisure underwear collection for the girl that wants the good looks from fashion, a perfect fit for her body, and a quality that's hard to beat," Wozniacki said in a press release that was certainly not written by a public relations firm. "JBS was the perfect partner to accomplish that."

Wozniacki should hope for more luck with her underwear range than she's had at the French Open however. An erroneous line call sent the Dane into a spin during a three-set loss to Kaia Kanepi.

Wozniacki challenged the chair umpire during a whiny exchange in the second set. A Kanepi shot was incorrectly ruled in and Wozniacki took the opportunity to childishly complain about it. The complaint itself was valid -- replays showed the ball landing beyond the line -- but the setting was more lockers and Trapper Keepers than red clay and Paris. At one point, Wozniacki asked the umpire if he had ever gone to school. It was a wonder she never got to "I know you are, but what am I?"

A transcript of the exchange that was clear on audio:

"You can not just sit there and be so arrogant. How can you see those balls there when the ball is like this out? It's not touching the line. If we had Hawk-Eye you would be so freaking embarrassed right now. So embarrassed, especially when you can see the mark. Have you been to school? Can I ask you, have you gone to school? You have gone to school, so you know that this [holds up fingers closely together] is out. It's not so difficult."

Wozniacki, who has dropped to No. 9 in the world and hasn't won a tournament since last August in New Haven, continued her outrage in the post-match press conference:

"When the ball is clearly out, I don't think there should be anything to argue about. If they cannot see, they should have other umpires on the lines or invent Hawk‑Eye on these courts. It's a disgrace that mistakes like this are made. It wasn't even like, you know, could have been in, could have been out. It was clearly out. Also, when a ball travels 5 miles an hour I think either the linesman or the main umpire should be able to see the ball, as well."
