'Pathetic': French Open erupts over ugly moment between rivals

The French Open match between Casper Ruud and young tennis phenom Holger Rune was played in a fiery manner and the handshake at the end left the tennis world fuming.

Ruud showed why he is becoming a clay court force with a powerful 6-1, 4-6, 7-6, 6-3 victory over the passionate teenager.

Rune didn't hide his emotions during the match that involved him gesturing towards the crowd and an outburst seemingly at his mother.

However, plenty of drama ensued on match point when Ruud's forehand winner clipped the line.

Rune wasn't as convinced and called for the chair umpire to come look at the mark, while Ruud waited for his opponent at the net.

The chair umpire eventually confirmed the ball was out.

And showing his frustration Rune presented Ruud with a rather lazy handshake as he just kept walking towards his bench.

This prompted Ruud to stare at Rune and shake his head in disappointment at the 19-year-old.

Tennis great Rennae Stubbs was quick to join the chorus of viewers in calling out Rune for his behaviour.

The rivals exchanged words during the match when Ruud reportedly asked Rune at the change of ends why he was challenging obvious calls.

Rune confirmed the interaction in his post-match press conference.

Despite the unsavoury scenes, Ruud was complimentary towards Rune after the match.

"I came here around 3pm-4pm, I did all the preparations. I started great but then Holger fought back well, raised his level and I had a really tough match in the end there," Ruud said to tennis great Mats Wilander on Eurosport.

“He has improved a lot. I’ve played him four times already in my career. I’m probably the player who has played him most on tour so I know a little bit how he plays but he has become much more dangerous, more unpredictable.

“He plays fearless, plays a lot of big shots and makes a lot of them so he makes it challenging for you and he’s going to be a dangerous player for many years.”

Holger Rune appears to yell at mother at French Open

In a bizarre moment early on in the match, Rune appeared to yell something, in Danish, in the direction of his player's box at a change of ends.

Many viewers on social media claimed the 19-year-old yelled 'leave' to his mother.

The tennis world didn't take kindly to the outburst and called out the Danish superstar for his outlandish behaviour on the big stage.

In the end, it appears Rune's mother left for a brief moment following the outburst.
