Lee Zii Jia got his World Championships campaign off to a winning start after flexing a dominant performance to beat Jonatan Christie in straight games, as Goh Jin Wei joined him in the second round in Copenhagen.

Lee was hot in the news last week after a dispute with the Badminton Association of Malaysia (BAM), but the Malaysian looked free of distraction to comprehensively seal the 21-13, 21-15 win.

The first game started out closely enough with both men testing each other out, but once Lee found his groove there was no stopping him.

The world number 13 preferred to play to his strengths, using his power and deception to probe for openings in Christie's game.

It worked well, as Lee's first game highlight came when he remarkably thwarted one of Christie’s smashes with a no-look return.

The Indonesian continued to be frustrated with his unforced errors, with Lee saving all his attacking weapons for the second game.

Then it became a relentless assault on Christie’s backhand as Lee thundered home his signature overhead kills, even conjuring up a great reflex return to leave his opponent baffled.

The victory was sealed in just 39 minutes, booking him a match gainst Canada’s Brian Yang next.

Goh also came through after she beat Hungary’s Vivien Sandorhazi 21-18, 21-15, but the independent shuttler has a massive task next against top seed An Se-young.

S. Kisona failed to make it into the next round after she suffered a 22-20, 19-21, 13-21 against Chinese Taipei’s Pai Yu-po.

Kisona should have clinched victory in straight games as she held a five-point lead in the second game, but her mistakes allowed Pai back in and the Malaysian cut a lethargic figure in the decider to concede defeat.

Ng Tze Yong joined Lee as a fellow Malaysia men's singles shuttler in the next round after coming through a scintillating 21-19, 26-24 victory over Zhao Jun Peng.

The world number 22 prevailed in a rollercoaster match, as he first found that extra bit of quality to edge the opening game.

The next game was equally as intense, and Ng had to bid his time before overcoming the plucky Chinese in the fifth match point.

Ng will most likely go on to play home shuttler Anders Antonsen next.
