Fourth round play began Day 8 at Roland Garros in sunny but windy conditions on Sunday. First up were 8th seeded German Angelique Kerber and 39th ranked Russian, Svetlana Kuznetsova. Kuznetsova won the title in 2009, but Kerber was a quarter finalist last year and won their two meetings in 2013. Both physically strong, this looked to be a good match up – and a competitive game it was, with spectacular retrieving and strong defences on both sides of the net. The Russian got the match underway and the hard hit games went with serve. The 6th game, with Kerber serving, went to 5 deuces and lasted more than eight minutes before the German held and then got the first break, but Kuznetsova broke straight back and took the next two games, for the set at 6-4. The Russian started the second set and took the first two games, the German the next two. Kerber broke in the 7th game and despite Kuznetsova holding in the first love game of the match, Kerber held serve to take the set 6-4. There were breaks in the first two games of the decider before Kuznetsova broke again to lead 4-1. The next three games went with serve before the Russian broke a final time to take the set 6-3 and the match in 2 hours 21 minutes.
The next match on Centre Court was between American top seed Serena Williams and 15th seed Roberta Vinci of Italy. Williams only lost six games on her way to the fourth round, but the Italian is a clay court and doubles specialist. Vinci started but Serena broke and ran up a 4-0 lead before Vinci got a game. Serena then wrapped up the set 6-1 in 29 minutes. In the second set the first six games went with serve and it looked as if Vinci would push Serena, but the American took the next three games to take the set 6-3 in 41 minutes.
