She beat Petra Kvitová in the final, and as a result made it into the top 20 for the first time.

At her last tournament of the year in Bali, she was drawn into Group C. Wickmayer defeated Kimiko Date-Krumm in her first match in straight sets. As she was supposed to face Anabel Medina Garrigues next, she was disqualified from the tournament due to doping allegations.

On 1 October 2009, it was announced that Wickmayer and fellow Belgian tennis professional Xavier Malisse were to defend themselves before the Flemish anti-doping tribunal for failing to properly fill out their whereabouts. Wickmayer replied in a press release that the failure to follow procedure was due to her not being able to log on to the relevant website, not being able to contact the right people when needed, and not being in the country when written admonitions arrived by mail from the Flemish anti-doping authorities. At the tribunal on 22 October 2009, the prosecution did not ask for a ban, but rather for a "principal restraint" of the facts that they were being accused of, and as such it was expected that this would not cause any problems for either athlete. However, on 5 November 2009, the decision of the tribunal was announced: an effective one-year ban for both players.Sportwereld – 'Yanina is helemaal gebroken' (Dutch).
