Stuttgart, April 24 Australian Open champion Angelique Kerber picked up her second title of 2016 with a 6-4, 6-0 victory over qualifier Laura Siegemund in final of the WTA clay-court tournament in Stuttgart today. In an all-German final, Kerber claimed her first win since her Melbourne triumph in January with an impressive display against Siegemund. This was Siegemund' debut in a WTA final and Kerber's first since the Australian Open as she defended her Stuttgart title. Kerber, the world No 3, came out on top in a tight first set, then raced into a 2-0 lead as Seigemund had to briefly receive treatment. Having broken Siegemund to go 5-0 up, Kerber used her first championship ball to seal the win which again includes the prize of a luxury Porsche sports car.
