Could the Williams sisters be on a collision course to an All-American Wimbledon Final?

Venus advanced to the semifinals for the first time since 2009 with a 7-6.-6-2 win over Yaraslova Shvedova of Kazakhstan.  Williams trailed 5-2 in the first set tiebreaker, but reeled off five straight points and then ran away with the second set.  Venus will fave Australian Open Winner Angelique Kerber in the semis.  The #4 seed dispached #5 Simona Halep in her quarterfinal match.

Serena, meanwhile, defeated Russian Anastasia Pavlyunchenkova 6-4, 6-4 to run her Wimbledon record in quarterfinals to 10-2.  Her opponent will be Elena Visnena, another Russian, in the semifinals.  Visnena is the first unseed player to reach the Wimbledon semis since 2010.
