Holger Rune, ranked number 4 in the world, expressed his disappointment with the US Open organizers after his opening match was scheduled on a smaller court. Rune took to social media, posting a picture of the tournament site map and sarcastically suggesting that people would struggle to locate Court No. 5, where his match was scheduled to take place.

Rune's cryptic tweet sparked mixed reactions from fans. While some accused the US Open of disrespecting the Danish star, others believed that Rune was making a bigger deal out of it than necessary.

Unfortunately for Rune, his disappointment off the court seemed to translate onto the court as well. The 20-year-old suffered a shocking loss in the first round to Spanish player Roberto Carballes Baena, losing in four sets. This defeat marked another early exit for Rune, who has struggled to find success since reaching the quarterfinals at Wimbledon.

It remains to be seen how the US Open organizers will respond to Rune's criticism, but it's clear that the Danish star's disappointment with his court assignment had an impact on his performance on the court.
