sets. After that match the pair did not meet for more than four years until the 2012 BNP Paribas Open where Sharapova won after Ivanovic retired after winning the first game in the second set. Ivanovic would then lose the next four meetings that followed. In 2014, Ivanovic defeated Sharapova for the first time since 2007 at the Rome Masters in straight sets. Their match at the Cincinnati Masters was a dramatic and controversial one. Ivanovic was up a set and a double break before a bad call was made that affected Ivanovic and allowed Sharapova back into the match to steal the second set. Then, in the third set, Ivanovic was up 1–0, 15–15 before she took a medical timeout, after which Sharapova took control of the set. Up 4–3 with a break, Sharapova double faulted on break point and sarcastically said to the umpire to "check her blood pressure" referring to the medical timeout that Ivanovic took earlier in the set. Sharapova broke right back to serve for the match. Sharapova had two match points but failed to convert both. Ivanovic would eventually prevail, recording her first win over Sharapova on the hard courts. The pair did not need to wait long to meet in 2015, with both drawn as the top 2 seeds in the Brisbane International. Both players qualified for the final, but it was Sharapova who once again clinched victory on the hard courts, despite dropping the first set to Ivanovic in a tiebreak.
