Defending champion and tournament third seed Anders Antonsen suffered a shock defeat at the hands of unseeded Indian Sameer Verma in the second round of the Denmark Open in Odense.

Verma progressed to the quarter-finals of the men's singles tournament after the remarkable 21-14, 21-18 second-round victory.

Antonsen never looked like winning as he led for just one point throughout the entire match in the Odense Sports Park.

Verma will meet Tommy Sugiarto next after the Indonesian beat France's Thomas Rouxel 21-18, 16-21, 21-19.

The clash is the only men's quarter-final without a seeded player.

Top seed and world champion Kento Momota of Japan set up a tantalising fixture with Indonesia's Jonatan Christie following a 23-21, 21-9 win over Srikanth Kidambi.

Sixth seed Christie crushed Momota's compatriot Kanta Tsuneyama 21-11, 21-9.

Ng Ka Long Angus, the number eight seed in Denmark, fell to an unlikely loss to fellow Hong Kong player Lee Cheuk You 21-16, 18-21, 21-8.

Home favourite Viktor Axelsen and Malaysia's Lee Zii Jia will meet in the next round after comprehensive victories.

Axelsen beat India's Lakshya Sen 21-15, 21-7 while Lee dispatched fellow Malaysian shuttler Liew Daren 21-11, 21-14.
