- Reigning Australian Open champion Angelique Kerber cruised into the ATP and WTA Miami Open semi-finals on Wednesday by dispatching US 22nd seed Madison Keys 6-3, 6-2. The German second seed will play a Thursday semi-final against two-time Australian Open champion Victoria Azarenka, the former world number one from Belarus who defeated British 24th seed Johanna Konta 6-4, 6-2. Azarenka is 6-1 lifetime against Kerber, but lost their most recent meeting in the Australian Open quarter-finals. "I know I have to play my best tennis against her," Kerber said. "I will be ready." Two-time Grand Slam champion Svetlana Kuznetsova meets Swiss 19th seed Timea Bacsinszky in the other semi-final. The 30-year-old Russian has won both their previous meetings.
