Venus looks to block progress of sister Serena

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 Wimbledonâs second week.
âSerenaâs playing for history; Venus isnât going to have that many more opportunities here,â she said.
