UMPIRE Carlos Bernardes made a never-before-seen error during the second round of the Shanghai Masters.

His mistake caused Stan Wawrinka to lose his clash with Flavio Cobolli, but neither player even noticed the official’s slip-up.

Wawrinka was beaten 6-7 (6-8), 7-6 (7-4), 6-3 by the 28th seed on Monday in China.

The tight match saw just a single break of serve outside of tie breaks, with Cobolli winning the crucial game in the deciding set.

However, it only came after Bernardes’ bizarre error during the first point of the final set.

Bernardes awarded it to Cobolli by mistake after the Italian had returned Wawrinka’s serve out.

He then won the next point to lead 30-0 instead of 15-15, but neither player or the commentators noticed the error.

It came as the umpire had asked for more electrolytes for Cobolli, making the request over walkie talkie after awarding the point.

Fans on social media were quick to spot the mishap, though, as footage of the incident was shared online.

This prompted former Wimbledon finalist Nick Kyrgios to slam Bernardes on X.

He wrote: “Bernardes should have been fired years ago. How does this happen? Potato.”

On court, Cobolli went on to take the final set to beat former world number three and three-time Grand Slam champion Wawrinka.

His reward was a last 32 match up with four-time winner Novak Djokovic on Tuesday.

Meanwhile, Wawrinka, who is now ranked 236th in the world, heads home from the tournament.
