Kerber crashes out in Qatar as seeds scattered

Angelique Kerber was one of at least seven seeds who crashed out of the Qatar Open on Tuesday, in the German's first singles tournament since winning her first Grand Slam title in Melbourne last month. The Australian Open champion lost her second round match -- she received a first round bye -- in straight sets 7-5, 6-1 to China's Zheng Saisai, who is ranked 70 places below the world number two. Also out was defending champion and number seven seed Lucie Safarova.
