Wozniacki has won several junior tournaments (including the 2006 Wimbledon girls' singles tournament and the 2005 Orange Bowl tennis championship), and made her debut on the Sony Ericsson WTA Tour at Cincinnati's Western & Southern Financial Group Women's Open on 19 July 2005, losing to the top-seeded and later champion Patty Schnyder in the first round.
In 2006, she was the first seed at the Australian Open (junior girls' singles), but lost the final to eight-seeded Anastasia Pavlyuchenkova of Russia. She was seeded second with Anna Tatishvili in the doubles tournament, but the pair was knocked out in the semifinals by the French-Italian pair of Alizé Cornet and Corinna Dentoni, who were seeded eighth.
She entered the Beijing, where after a first round bye, she defeated Sara Errani 6–4, 6–2. In the third round, Wozniacki faced Petra Kvitova (who had heavily defeated her at Wimbledon). Avenging the loss, Wozniacki won the match 6–3, 6–2, replacing World No. 1 Serena Williams as the new World No.1 in the process. She is the second youngest player in WTA history to reach the number 1 position without having won a Grand Slam. She also became the first, and only Danish woman to reach the top ranking. In the quarterfinals, she defeated resurgent former World No.1 Ana Ivanović 7–6(1), 6–4. This was Wozniacki's first win over the Serbian. She then defeated Shahar Peer in the semifinal by a score of 7–5, 6–2 and Vera Zvonareva 6–3, 3–6, 6–3 in the final to win her sixth title of the year and twelfth overall.
