Tennis: Berdych into semis after injury forces out Youzhny

Fourth seed Tomas Berdych has coasted into the last four of the ATP Halle tournament after quarter-final opponent and sixth seed Mikhail Youzhny withdrew through injury. Russia's world number 14 pulled out with a back injury and is unable to play Berdych - last year's beaten finalist at Halle - in Friday's quarter-final, giving the 21-year-old Czech extra rest before Saturday's semi.
