If you're a tennis fan than you know about "tennis grunting." Tennis grunting is when the tennis players grunt every time they hit the ball. Maria Sharapova is probably the " grunter supreme," but she is actually in  support of a ban for women's tennis. Maria's grunts have actually been measured at more than 101 decibels, which is comparable to a chain saw.

Taylor Townsend came to the U.S. Open this week ranked as the number one junior women's tennis player in the world. But she almost didn't make it here because the U.S. Tennis Association told her that she couldn't compete at the U.S. Open or any tennis tournament until she got into better shape.

On Wednesday, tennis star Serena Williams had a fright after security cameras picked up what she thought was someone trying to break in to her Los Angeles home. In the heat of the moment, she barricaded herself in a panic room and called the authorities.

On Thursday, tennis star Serena Williams briefly changed her Twitter avatar to a photo of herself wearing only a bra, panties and high heels. The photo's tasteful lighting prevented her 2 million Twitter followers from getting too much of an eyeful, but it still managed to draw the ire of Sporting News columnist Greg Gouch.
