Petra Kvitova of the Czech Republic has leaped above Romania's Simona Halep into third place in the WTA rankings despite not playing over the last week. Germany's Andrea Petkovic moves back into the top 10 after winning the title in Antwerp on Sunday.
Petkovic won the WTA Diamond Games tournament when her final opponent Carla Suarez Navarro pulled out before the match with a neck injury. Despite that, the 26-year-old Suarez Navarro climbs to a career-best ranking of 13th.
Australian Open champion Serena Williams remains on top of the rankings ahead of Maria Sharapova, who lost in last month's final in Melbourne.
