Holger Rune was told to “grow up” by Casper Ruud while the Norwegian was advised to “show some respect” after the two fought out a tense French Open quarter-final in which the Danish teenager even appeared to order his own mother to leave the stadium. 

World No.8 Ruud became the first Norwegian man to reach a Grand Slam semi-final when he defeated Rune 6-1, 4-6, 7-6 (7/2), 6-3 in a tie which ended just before 1:00 on Thursday morning. Rune took out his frustrations on the court, repeatedly grimacing and shouting at himself and the umpire as tensions mounted between the two players.
