PARIS - Angelique Kerber has risen from sixth to second in the latest WTA world rankings released on Monday after claiming her maiden Grand Slam title at the Australian Open. The German stunned world No 1 Serena Williams in the final, but the American still holds a large lead at the top of the rankings. Venus has slipped out of the top 10 after her first-round defeat to unseeded Briton Johanna Konta. Kerber's rise means that Simona Halep, Garbine Muguruza and Maria Sharapova have all slipped down. Spain's Carla Suarez Navarro is the newest entry into the top 10 at number eight. WTA world top 10: 1. Serena Williams, 2. Angelique Kerber, 3. Simona Halep, 4. Agnieszka Radwanska, 5. Garbine Muguruza, 6. Maria Sharapova, 7. Flavia Pennetta, 8. Carla Suarez Navarro, 9. Petra Kvitova, 10. Lucie Safarova.
