The French Open will remain at the bottom of the grand slams until they still using Hawkeye, in my opinion. Too many matches are being determined by missed line calls.

Shapovalov, however, found support from his fellow players, including U.S. Open champion Dominic Thiem, whose match against Casper Ruud was also blighted by couple of uncertain calls.

"I would support 100% HawkEye on clay, because at the match from Denis against Roberto yesterday there was a mistake, and then today in my match there was a mistake in my favour actually," world number three Thiem told reporters.

"Casper showed me the mark on his phone after the match. It's not the umpire's mistake, because sometimes you just cannot see the mark. It's too difficult, especially after the set break, because they clean the court, they brush the lines.

"... I hope that next year we will have it (HawkEye) in every clay court tournament."

Brad Gilbert, a former world number four and currently an acclaimed coach, also felt "modern technology works on clay better than umpire's interpretations of marks".

Greek Stefanos Tsitsipas agreed that he would rather depend on technology.

"I think it's time for HawkEye on clay. I don't understand why they haven't proceeded," said the world number six.

"... We have to keep growing and keep adding new things to the sport that will help make the sport better and more fair."

Ruud's points against Thiem were not as crucial as Shapovalov but the Norwegian could relate to the Canadian's frustrations.

"I think it's a bit strange that they have the HawkEye available here but they only show it for TV and I don't understand why we can't use it," Ruud said.

"I think definitely... we should start using HawkEye for the clay court tournaments as well because then we don't need to have all these arguments with umpires."
