Video - The Huge Umpiring Error Against Wawrinka in Shanghai 2024

Flavio Cobolli and Stan Wawrinka were engaged in a tight battle in the second round of Shanghai in 2024.

While the Swiss player was serving his first game of the decisive set, he won the first point before losing the second.

Although the score should have been 15-15, the chair umpire, Carlos Bernardes, announced a score of 0-30 in favor of Cobolli, which didn't trigger any reaction from anyone.

The Italian ended up breaking Wawrinka and won 6-7, 7-6, 6-3. An error that would have significant consequences for the Swiss player.
