Caroline Wozniacki says she’s knocked off one of her final career goals before retiring from tennis after winning a doubles match with close friend and long-time rival Serena Williams.

The powerhouse duo entertained the crowd at Auckland’s ASB Classic with a straight sets win on Monday, playing together for the first time after years of high-stakes singles struggles.

Former world No.1 Wozniacki has only prevailed once in 11 meetings with American Williams, who ranks as arguably the world’s greatest ever female player.

The 29-year-old Dane plans to retire after the looming Australian Open in Melbourne so it was no surprise she was beaming after the 6-2 6-4 win over Japanese pair Nao Hibino and Makoto Ninomiya.

“It wouldn’t be the same if I didn’t get to play with her at least once on the same side,” she told Sky Sport NZ.

“She’s beaten me a lot of times on the other side so it’s nice that we can win together.”

Wozniacki hasn’t played doubles in more than three years, something that surprised Williams, who described her partner’s form as unbelievable.

“I can’t let the rest of our amazing careers go without playing with her – a grand slam champion and a long-time No.1,” Williams said.

“Of course I want to share the court with her.”

Wozniacki will play her last top level match against Williams in an exhibition match in Copenhagen in May.
