Wozniacki claimed she was the latest victim of the growing problem as she crashed out against Barbora Zahlavova Strycova, the unseeded Czech who claimed another famous scalp to move into the quarter-finals with a 6-2, 7-5 victory.
Danish 16th seed Wozniacki was unhappy with the length of time Zahlavova Strycova took between points, claiming the Czech's routine stopped her establishing any rhythm.
"I thought she was very slow. But I guess the referee, she has the time on it. If she's within the time, I guess it's okay. It's up to the referee or up to the umpire to say if she is or not," said the Dane.
"I wouldn't mind. I think that's fine. You have a clock. It shows exactly how much time you take in between points," said Wozniacki.

Wozniacki's calls were echoed by reigning Australian Open champion Stan Wawrinka, who cruised to a 6-3, 6-3, 6-4 win over Denis Istomin in his delayed third round match.
"I think it would be interesting and good to see," Wawrinka said.
"One year ago, the ATP started to have a strict 25-second rule, but it was for what? For nothing.
"You can see some players taking more time than the 25 seconds, getting one time violation, that's it. Sometimes the average time is 28 or 30 seconds.
