Critics are accused of sexism, given grunting is hardly restricted to the women.
Eight-time Grand Slam winner Jimmy Connors grunted furiously in the 1970s and 1980s, while Ivan Lendl once complained that Agassi’s grunting put him off.
“Maybe it’s just not as high-pitched, so you kind of don’t worry about it,” Stosur said.
British No. 2 Heather Watson claimed not to have noticed Sharapova’s cacophony during a three-hour marathon with the Russian last week.
“I think I’m just too used to it,” said Watson, who trains at the Bollettieri academy and works with Sharapova’s former coach Mauricio Hadad. “I know some players don’t like it, but most girls grunt, so I really don’t take much notice.”
