File Pic[/caption] Internet Desk: Five-time champion Venus Williams reached the Wimbledon semi-finals for the first time since 2009 with victory over Kazakhstan's Yaroslava Shvedova. Eighth seed Williams - at 36 the oldest Grand Slam semi-finalist for 22 years - beat unseeded Shvedova 7-6 (7-5) 6-3. An all-Williams final remains possible after top seed Serena beat Russian Anastasia Pavlyuchenkova 6-4 6-4. In Thursday's semis, Serena will play Russia's Elena Vesnina and Venus will take on Germany's Angelique Kerber. As the years advance, finishing anything can present a problem. But Tuesday at the All England Club, Serena Williams did it elegantly and emphatically. A 123 mph ace scorched the grass in the service box, sending her back into the semifinals. It was the poignant punctuation of a 6-4, 6-4 thrashing of No. 21 seed Anastasia Pavlyuchenkova. While lately elder sister Venus Williams has been getting a lot of credit for being, well, old, Serena is not exactly a starry eyed kid anymore. At 34, she is five years older than next-oldest quarter finalist, Elena Vesnina. Asked about a potential final meeting, she added: "It will be great. Venus is such a tough opponent I want her to win so bad - not in the final if I am there, but if I'm not, I do." Kerber, the fourth seed, beat Romanian fifth seed Simona Halep 7-5 7-6 (7-2) in the opening match on Centre Court. Unseeded Russian Vesnina thrashed Slovakian 19th seed Cibulkova 6-2 6-2 in the remaining quarter-final on court one.
