Ong Yew Sin-Teo Ee Yi pulled off one of the big comebacks at the BWF World Championships as they beat Denmark's Joel Eipe-Rasmus Kjaer 21-12, 21-19.
The world number 12 were comfortable in their 21-12 first-game victory over the Danes, using crafty net plays to set themselves for big smashes.
The Danes were then heard telling each other they were ready to "die on court" in the second game, and they did so in true fashion by taking an 18-10 lead.
But Ong-Teo were far from giving the game up to go into a decider.
Instead they were patient in the rallies, and waited for the opportunity to pounce with Teo prowling the front court and Ong setting himself for the kills at the back.
Their strategy worked to perfection as the pair went on a 11-1 run to seal the 39-minute match.
Ong-Teo next take on eight seeds Satwiksairaj Rankireddy-Chirag Shetty in the last 16.
Goh Sze Fei-Nur Izzuddin joined them in the third round after toiling to a 21-14, 19-21, 21-16 win achieved in almost an hour.
They now go on to face third seeds and reigning Olympic champions Lee Yang-Wang Chi-lin.
In the mixed doubles, Tan Kian Meng-Lai Pei Jing had no problems beating Saurabh Sharma-Anoushka Parikh 21-8, 21-18.
The victory also saw Lai produce an amazing net retrievel that she described as a "lucky shot" which nonetheless left her partner stunned.
The ninth seeds now go on to face third seeds Japanese Yuta Watanabe-Arisa Higashino.
