Sabine Lisicki's Wimbledon build-up came to grief with an unexpected defeat amidst prolonged controversy in the quarter-finals of the Birmingham WTA tournament on Saturday. Lisicki, the champion here two years ago, had hoped to win the title as she prepares for Wimbledon which she believes she can win after reaching the semi-finals and quarter-finals in the past two years. However, she lost a ten-minute argument with the umpire and the tournament referee, and the match in three sets to Alison Riske of the United States.
