“At first it was tough,” said the #NextGenATP Dane after the match. “I was struggling a lot, making a lot of errors. He came out and played very well in the beginning, so I was a bit stressed.
“I tried to think like a professional, I tried to find a way. I’ve played too many matches in my career where I’ve lost the first set, so I just told myself, ‘Let’s stick in there, play every ball in the court, and let’s see what happens’.”

World No. 90 Rune came into the match with an 0-4 tour-level record in 2022 and looked to be in trouble again after Bergs won the first five games of the match and eased to the first set.
Rune found his game in the second set and levelled the match by converting his seventh set point, and his confidence looked to have been fully restored as he surged to a 4-1 lead with a double-break in the deciding set.
There was a slight wobble as the Belgian World No. 169 reclaimed one break back, but the 18-year-old held his nerve to claim victory, letting out a roar of relief when Bergs sent a forehand long on match point.
Rune will look to back up his win in the second round, where he faces a first ATP meeting with fourth seed Aslan Karatsev.
