Tatiana Golovin, who has been working with Mats Wilander (of "Roger Federer has no balls" infamy), has changed coaches again. She will now be coached by Glen Schaap, who has worked with both Nadia Petrova and Dinara Safina. The word is that Wilander did not want to do a lot of traveling. Golovin's game improved seriously under his tutelage; one hopes she will stay on track now that he is gone.
Coaches and potential coaches who do not wish to travel much naturally do not stay with a player long. Gigi Fernandez did not stay that long with Sam Stosur because she did not wish to travel, but she did improve Stosur's game.
