Ana Ivanovic beats Serena Williams

Ana Ivanovic may be ranked as the 14th-best player in the world, but nobody expected her to truly challenge Serena Williams. Williams was on a roll, having won 25 straight matches, including a third-round victory over Daniela Hantuchova that moved her past Margaret Court for the most wins at this tournament in the open era. But Ivanovic did the unthinkable and took down the legend 4-6, 6-3, 6-3. It seemed all but over when Williams won the first set—after all, she was 51-1 when she won the first set at the Australian Open. We can update that stat to read 51-2. Ivanovic had a streak of her own entering the Grand Slam, winning the tuneup tournament in New Zealand and playing a terrific match against Sam Stosur in the third round. Despite that, it seemed highly improbable that she could be anything more than a speed bump to Williams, who was aiming for her sixth Australian Open title. Ivanovic had never taken a set from Williams in their previous four meetings. But fifth time was the charm: http://bleacherreport.com/articles/1928742-serena-williams-vs-ana-ivanovic-recap-and-results-from-australian-open-2014?utm_source=cnn.com&utm_medium=referral&utm_campaign=editorial&hpt=hp_t2
