[EX Q]: Passage: In 2014, Ivanovic enjoyed a resurgence and attained a number of career-best achievements. She began the year by winning her first title in three years at the ASB Classic, defeating former world No. 1 Venus Williams in three sets before upsetting the reigning world No. 1 Serena Williams en route to her second Australian Open quarterfinal where she lost in three sets to thirtieth seed, Eugenie Bouchard. During the clay court season, Ivanovic reached her third final of the year at the Porsche Tennis Grand Prix, losing to two-time defending champion Maria Sharapova; the quarterfinals of the Mutua Madrid Open and the semi-finals of the Internazionali BNL d'Italia, defeating Sharapova for the first time since 2007 en route but was ultimately upset by Lucie Safarova in the third round of the French Open. She rebounded by winning her first career singles title on grass at the Aegon Classic before reaching the final of the Western & Southern Open (her first top tier Premier final since 2009) and thus returned to the top ten of the WTA rankings for the first time in five years as a result. In September, Ivanovic reached her sixth singles final of the year (a new career-best) at the Toray Pan Pacific Open, where she defeated Caroline Wozniacki to claim her fourth title of the season, the most titles she won in a single season.
