her first win over Azarenka in Eastbourne in 2011, winning after Azarenka retired with injury. At the 2011 WTA Tour Championships, Bartoli qualified as a reserve for Maria Sharapova and in the only match she played, she upset Azarenka in three sets. The match had no meaning because Bartoli could not qualify for the semi-finals as Sharapova had lost her two matches and Azarenka had already qualified for the semi-finals. The pair met three times in 2012, with Azarenka winning two of the matches.

The rivalry between the two players started to intensify in 2012, with six meetings between the pair that year, four of them being in finals. Azarenka won four of the six meetings that year, three of them in finals. Their most famous meeting occurred early that year, in the final of the 2012 Australian Open.
