It's about time they got to this to improve the image of women's tennis. The loud grunting from some players is a tool for gaming your opponent and becomes clear when the volume increases when you get into trouble in a match. Some players are silent and hit the ball just as hard. So, whether an acquired habit or an emotional release, the use of the grunt as it exists is now getting serious attention in women's tennis and I would love to see this applied to the men's side of the tour as well.
