Electronic line calling has come under fire once again, this time at the Canadian Open.

There were multiple complaints about electronic line calling at Wimbledon this year, which implemented the technology for the first time in the tournament’s history.

Wimbledon is the third Grand Slam to use the system, with Roland Garros choosing not to have electronic line calling.

The Canadian Open is using electronic line calling, but a WTA player believes it made a mistake in her first round match this year.

Canadian wildcard Carson Branstine was playing former world number three Maria Sakkari in her first round match in Montreal this year.

Branstine, who played Aryna Sabalenka at Wimbledon this year, was once again on the losing end of the result against Sakkari.

Sakkari beat Branstine, 6-2 3-6 7-5, in a tight three set match at the Canadian Open.

One of the big talking points from the match came when Sakkari was serving for the match at 6-5 15-30 in the third set.

The crucial subsequent point was a controversial one, as Branstine was convinced that Sakkari’s backhand had gone out.

Electronic line calling adjudged the shot to have been in and as Branstine had hit the next shot she was unable to see the call on the big screen.

Branstine was frustrated on the court and expressed her views on the situation in a post on X (formerly known as Twitter).

She wrote, “They didn’t let me replay this clear mistake by the electronic line call because I played the shot after…BRUH obviously I tried to play the shot the damn thing didn’t call the ball out (crying face emoji). What’s a girl supposed to do.”

Branstine is now scheduled to head to Landisville, Pennsylvania, to play the lower-level ITF W100 event next week.

However, she is currently in the qualifying draw and needs just one more withdrawal to make her way into the main draw.
