BELGRADE, Serbia(AP) Former top-ranked player Ana Ivanovic hired Craig Kardon as her new coach Wednesday.

Ivanovic will start working with Kardon at the Dubai Tennis Championships next week, the Serb said on her Web site. The 47-year-old Kardon was the former coach of Martina Navratilova, Lindsay Davenport, Mary Pierce and Jennifer Capriati.

Ivanovic parted ways with her former mentor Sven Groeneveld.

The 21-year-old Ivanovic won the 2008 French Open and held the No. 1 ranking for nine weeks before Serena Williams reclaimed it.

Ivanovic is No. 8 after an early exit from the Australian Open.
