Ana Ivanovic has ended her coaching relationship with Antonio van Grichen. The two began to work together during the off-season, but apparently didn't mesh.
Ivanovic announced the separation after defeating Nudnida Luangnam 6-0, 6-2 in the first round of Pattaya City. Van Grichen, who also coached Victoria Azarenka and Vera Zvonareva, was still trying to get a handle on which changes she needed to make to her game. He believed that Ivanovic had lost too much weight and needed to put more muscle back on.
The former world No. 1 has been through a slew of coaches over the past couple of years including Sven Groenefeld, Craig Kardon and Heinz Gunhardt. She is planning on hiring a full-time hitting partner to keep some stability while she searches for a new coach.—Matthew Cronin
