LONDON: Venus Williams vanquished Yaroslava Shvedova 7-6(5) 6-2 in a brutal baseline shootout at Wimbledon on Tuesday to reach her first grand slam semi-final for six years. In a scrappy match, the five-times champion - the oldest woman in the draw at 36 - drew on her experience to see off the Kazakh player contesting her first Wimbledon quarter-final. There was little to choose between the two as they slugged it out in the first set, with neither finding much rhythm. But Shvedova's challenge crumbled after she narrowly lost a tiebreak she had led 5-2. The 28-year-old, ranked 96, made a string of errors in the second set while her seasoned American opponent - sensing her opportunity - found her range and produced a succession of winners off both flanks. Williams, the 8th seed, advances to her first grand slam semi-final since the 2010 US Open and will face Germany's fourth-seeded Angelique Kerber. The American said she was delighted with the quarter-final victory. 'If you are Serena Williams, this happens a lot - but as Venus Williams, this is an awesome day,' she said referring to her sister, the world number one, who was playing later.
