MIAMI, FL, USA – Former World No.2 Svetlana Kuznetsova recovered from a hotly contested opening set to earn her first victory over top seed Serena Williams since 2009, upsetting the 21-time Grand Slam champion in the fourth round of the Miami Open, 6-7(3), 6-1, 6-2.

Beginning the season with a title at the Apia International Sydney, the two-time Grand Slam champion hadn’t defeated a reigning World No.1 since winning the French Open almost seven years ago and needed three sets to beat both Carina Witthoeft and Caroline Garcia just to reach the fourth round.

Into the quarterfinals for the first time since 2009, Kuznetsova next plays the winner of No.12 seed Elina Svitolina and No.30 seed Ekaterina Makarova – neither of whom had made their WTA main draw debut when the Russian last won in Miami in 2006.
