Denmark's Mathias Boe and Carsten Mogensen got off to a winning start Wednesday in their bid to end the year with their fourth straight BWF World Superseries Finals men's doubles crown.
The pair began their campaign with a 21-16, 21-19 Group B victory over South Koreans Ko Sung-Hyun and Lee Yong-Dae on the first day of the season-ending tournament at the Cheras Badminton Stadium in Kuala Lumpur.
It was a good day for Danes overall, with victories for Jan O Jorgensen and the women's pair of Christinna Pedersen and Kamilla Rytter Juhl, while men's world number one Lee Chong Wei breezed through his match on home turf as expected.
Boe and Mogensen, the former world number one men's doubles who have dropped to number three, have not won a Superseries title this year, but said they were hopeful of breaking the drought despite stiff opposition.
"We will be up against a skilful Japanese pair tomorrow (Hiroyuki Endo and Kenichi Hayakawa) so we will have to prepare for that," Mogensen said.
Endo and Hayakawa also opened their campaign with a victory, beating compatriots Hirokatsu Hashimoto and Noriyasu Hirata 19-21, 21-19, 21-12.
In the men's singles, Denmark's Jorgensen defeated Thai veteran Boonsak Ponsana 21-19, 13-21, 21-11.
And the women's pair of Pedersen and Rytter Juhl beat Thailand's Duanganong Aroonkesorn and Kunchala Voravichitchaikul 21-16, 21-17.
Mixed doubles world champions Tontowi Ahmad and Liliyana Natsir of Indonesia meanwhile crashed out to a 9-21, 26-24, 21-16 defeat at the hands of Thailand's Sudket Prapakamol and Saralee Thoungthongkam.
Meanwhile, in Group A, Lee, who is also seeking a record fourth BWF World Superseries Finals crown, beat China's Wang Zhengming 21-10, 21-18.
Lee, who won the tournament from 2008-2010, also became the first player to use video line-call review with a decision in his favour.
The technology has been debuted in this tournament as part of efforts to stamp out faulty line-calls.
Earlier Wednesday, China's Wang Shixian beat Taiwan's Tai Tzu-ying 21-16, 23-21.
In the women's doubles, Chinese teammates Ma Jin and Tang Jinhua beat Indonesia's Pia Zebadiah Bernadeth and Rizki Amelia Pradipta 21-3, 22-20.
The two top pairs of groups A and B will play in the crossover semi-finals of the $500,000 championship on Saturday.
The finals bring together the top eight performers in each category based on points earned from the 12 Superseries tournaments.
