Wozniacki was seeded second in Girls' Singles in the year's last major tournament. In the first round she won the first set against Russian Alexandra Panova, but was disqualified in the second set for verbally abusing an umpire. Wozniacki was said to have used an expletive in referring to a linesman who made a disputed call;[8] however, on her blog, she claimed to say "take your sunglasses of [sic]" and was mistaken for talking to the linesman, when she in fact was criticizing herself after the next point.[9]

Her first title on the senior tour came shortly after on 29 October, when she won the $25,000 ITF-tournament in Istanbul by beating Tatjana Malek in the final.

Wozniacki was set to face Venus Williams on 27 November in an exhibition match in Copenhagen,[11] but five days before the event, Williams canceled because of an injury.[12] The two did, however, face each other in the Memphis WTA Tier III event on 20 February. Williams beat Wozniacki, ending the nine-match winning streak Wozniacki had at the time.

On 30 November, Wozniacki was named ambassador for Danish Junior Tennis by the Culture Minister of Denmark at the time, Brian Mikkelsen.
