Holger Rune will play Felix Auger-Aliassime in the semi-finals of Swiss Indoors Basel on Saturday afternoon, but the umpire thought it was Casper Ruud during his Quarter-Final win over Tomas Martin Etcheverry.
In a hilarious clip during the changeover, the umpire said to Holger Rune who was protesting at the umpire, Damien Dumusois about long points to which he leaned over and said: "Most of the time you're good, Casper."
Albeit with hesitation on his end as he got confused as to who it was. He simply replied: "I'm not Casper" and looked away and frowned not seeing the funny side of the mistake.
