LONDON - Former No.1 tennis player Ana Ivanovic has split with her coach Craig Kardon.
The Serb had hired Kardon, who is the former coach of 18-time Grand Slam champion Martina Navratilova, on a trial basis to replace Sven Groeneveld.
Ivanovic dropped from No.8 to No.13 in this week's WTA rankings after her French Open title defence ended in the fourth round.
"I'd like to thank Craig for all his hard work," Ivanovic said on her website yesterday.
"He's a great guy and I enjoyed working with him," she said.
The 21-year-old will use temporary coaches for Eastbourne and Wimbledon later this month. - Sapa-AP
