The Swedish Olympic silver medalist in team events in Paris last summer started somewhat hesitantly in Singapore – but grew into the match against Quek.
The players took one set each, but Källberg won the crucial third set and went on to win the match via 11–9, 4–11, 11–8, 11–7.
In the second round of the Singapore Smash – one of the four grand smash tournaments on the world tour – Japanese player Maharu Yoshimura awaits.
We've met a few times, but it's been a couple of years. We'll see what I can dig up about him and remember from our matches, says Källberg in SVT's broadcast.
He's a spectacular player with a special style. I'm looking forward to meeting him.
On Monday, Truls Möregårdh enters the tournament as the second Swedish player in the men's singles. Kristian Karlsson and Mattias Falck did not qualify.
Monday's matches:
12.10: Linda Bergström–Xiaona Shan, Germany
12.45 Truls Möregårdh–Ovidiu Ionescu, Romania
