Ana Ivanovic has made another coaching change in a bid to turn around her flagging results. The 22-year-old former No. 1, who has dropped out of the Top 20, is now working with Heinz Gunthardt -- former coach of Steffi Graf.
Ivanovic was previously working with Sven Groenefeld as part of the adidas player development program. That relationship had been resurrected last summer after a short stint with coach Craig Kardon in the spring. Ivanovic also hired Damian Prasad as a new fitness trainer in December after parting ways with Scott Byrnes last July.
