clay season. Notably, she defeated upcoming players Mona Barthel (who she lost to at Indian Wells) and Laura Robson, as well as higher-seeded players Nadia Petrova at Stuttgart and Angelique Kerber twice at the Fed Cup week two playoffs and at the Mutua Madrid Open. As a result of Ivanovic's more consistent tennis in the clay season, she reached the quarterfinals in Stuttgart despite not being seeded, and managed to reach the semifinals of the Premier Mandatory Madrid Open for the first time in her career. In both Stuttgart and Madrid, her runs were routed by 2012 French Open champion Maria Sharapova. Unfortunately, after good runs at two clay-court tournaments, she dropped her opener in Rome against Urszula Radwańska. At the French Open she stormed past three opponents to the fourth round, only to fall in straight sets to Agnieszka Radwańska for the third time in the year. At Wimbledon, she won her first round match-up against Virginie Razzano, but in the second round Ivanovic would be knocked out of the tournament by Eugenie Bouchard.

At Carlsbad, she defeated Roberta Vinci before getting edged out by world No. 2, Victoria Azarenka, in the semifinals. In Toronto, she made quick work of Hsieh Su-wei and Flavia Pennetta in straight sets, before losing to Li Na in three sets. Ivanovic was up 5–2 in the third set, but was unable to serve out the match and eventually lost when she sent a backhand long in the tiebreak. Ivanovic dropped her opener in Cincinnati to Alizé Cornet. At the US Open, Ivanovic made it to the fourth round, narrowly scraping past American player Christina McHale in the third round by erasing two of her opponent's match points. Ivanovic made a whopping 51 unforced errors in her match against Christina McHale. In the fourth round, Ivanovic lost to Victoria Azarenka again in three sets. By winning the first set in her fourth round loss to Victoria Azarenka, Ivanovic won her first set against a top ten opponent at a major since she won the 2008 French Open, ending a streak of 15 consecutive sets lost against a top-ten seed. Ivanovic then headed to Asia for the Premier events in Tokyo and Beijing after a
