Venus looks to block progress of sister Serena

Elder sister Venus will directly block Serena Williams’s calendar grand slam path today in a Wimbledon clash that is impossible to watch. Former Wimbledon champion Lindsay Davenport believes the siblings’ first meeting in six years will have even the aficionados squirming in their seats.

Serena, 33 and already the Australian and French Open champion this year, said Briton Heather Watson should have won their third-round battle, while also tipping Venus as the more in-form of the two five-time Wimbledon champions, whose 26th meeting will launch Wimbledon’s second week.

“Serena’s playing for history; Venus isn’t going to have that many more opportunities here,” she said.

Fifth seed Caroline Wozniacki must beat Spain’s Garbine Muguruza to reach her first Wimbledon quarter-final in a packed fourth-round line-up. Maria Sharapova takes on Zarina Diyas, while fresh from dispatching defending champion Petra Kvitova, Jelena Jankovic meets Agnieska Radwanska.

The men’s schedule sees Wimbledon showman Nick Kyrgios face Richard Gasquet, their tussle topping the bill on Court Two and possible the day, with both men playing flamboyant, crowd-pleasing tennis.
