As a fan of tennis in general (and Stephens in particular as a young, American up-and-comer), I propose that we call this timeout the Azarenka Rule. Which is probably more appropriate than fruitlessly seeking that elusive medical diagnosis known as Azarenka Syndrome.
Serena Williams is out at the Australian Open, beaten by 19-year old American Sloane Stephens. (Williams took it out on her racket.) Stephens, Victoria Azarenka, Roger Federer and Andy Murray all reached the semis.
