2016 Wimbledon Women's Singles First Round - Russia's Svetlana Kuznetsova beat Caroline Wozniacki 7-5 6-4 Tuesday June 28,2016

Russia's Svetlana Kuznetsova got a late birthday present under Wimbledon's centre court roof on Tuesday June 28,2016 with a 7-5 6-4 win over former world number one Caroline Wozniacki, who is projected to drop out of the top 50 with the defeat.

Russia's Svetlana Kuznetsova (L) shakes hands with Denmark's Caroline Wozniacki (R) after winning the women's singles first round match at Wimbledon on Tuesday.

The veteran 13th seed's power undid the Dane, who had been seeking her first win at a grand slam this year after being dumped out of the Australian Open in the first round and missing Roland Garros due to injury.

The WTA women's tour said the 25-year-old, rated the best in the world in 2010 and 2011, could drop as low as 59, depending on other results, when the new rankings are released the day after the men's final.

Coming into the tournament ranked 45 after injuries to her ankle, knee and wrist, it was the first time Wozniacki, 25, had been unseeded at a major since the 2008 Australian Open and she was visibly gloomy after the match.
