Mathias Christiansen and Alexandra Bøje crowned a remarkable run of form with the biggest title of their partnership on finals day at the POLYTRON Indonesia Open 2026.
The Danish pair defeated China’s Cheng Xing and Zhang Chi 21-19, 23-21 to win their first Super 1000 title, adding another major milestone to what has become a golden year for the European champions.
It was a final decided by fine margins. Christiansen and Bøje had to stay composed through two tight games, particularly in the second, where Cheng and Zhang pushed them deep into the closing stages. But the Danes have built their season on resilience and clarity in pressure moments, and once again they found the answers when it mattered.
The victory continues an outstanding spell for Christiansen and Bøje, who had already arrived in Jakarta in strong form after a series of finals across recent weeks. Their Indonesia Open title now stands as the clearest statement yet that they are not simply enjoying a good run, but establishing themselves among the leading mixed doubles pairs on the World Tour.
For European badminton, it was the headline result of the day. A Super 1000 title in Jakarta, one of the sport’s most intense and prestigious arenas, adds further weight to a season that has already included a European crown and repeated deep runs at the highest level.
An reaches title number 50
The opening final of the day brought another landmark for An Se Young, who held off Akane Yamaguchi 23-21, 21-12 to defend her Indonesia Open women’s singles title.
It was An’s 50th international title, a remarkable total for a player still only 24 years old. The win also moves her to within one title of Viktor Axelsen’s tally, underlining the scale of what she is already building in the sport.
The match began as the contest many expected between two of the defining women’s singles players of this era. Yamaguchi, An’s most-played rival, pushed the first game into a tense finish, but An came through 23-21 and then accelerated away in the second.
There was a familiar pattern to the performance. An absorbed pressure early, stretched the rallies when required, and then gradually removed the space Yamaguchi needed to change the rhythm. Once the Korean had taken the first game, the second became increasingly one-sided, with An’s control and physical presence taking over.
After her astonishing semifinal comeback against Chen Yu Fei, where she recovered from 7-17 and 16-20 down in the deciding game, this final was a different kind of statement. Less dramatic, but just as impressive. She turned one of the sport’s toughest rivalries into a straight-games title win and left Jakarta with another major trophy.
Victor Lai stuns Christie for breakthrough title
The biggest individual breakthrough of finals day came in men’s singles, where Canada’s Victor Lai defeated home favourite Jonatan Christie 21-19, 21-8 to win his first BWF World Tour title.
It was not just a first title. It was a Super 1000 title, claimed at 21 years old, away from home, against an Indonesian player inside one of badminton’s loudest arenas.
Lai had already made history by becoming the first Canadian to reach a final at this level. He went one step further on Sunday, producing a performance of striking calm against Christie, who had been carrying the hopes of the home crowd and aiming to become Indonesia’s first men’s singles champion at the event since Simon Santoso in 2012.
The first game was the key. Christie stayed close and had the crowd behind him, but Lai showed no signs of being overwhelmed by the occasion. He played with patience, kept his shape in the rallies, and took his chances late in the game to edge it 21-19.
From there, the final changed quickly. Lai’s confidence grew, while Christie struggled to find a way back into the match. The Canadian controlled the second game 21-8, closing out the biggest win of his career with surprising authority.
For Christie and the Indonesian crowd, it was a painful near-miss. For Lai, it was a career-changing week and one of the most unexpected Super 1000 title runs in recent memory.
Fukushima and Matsumoto win three-game battle
Yuki Fukushima and Mayu Matsumoto came through the longest final of the day, defeating world number ones Liu Sheng Shu and Tan Ning 21-15, 18-21, 21-18 in the women’s doubles final.
The Japanese pair had lost twice to Liu and Tan earlier this year, but they found a way through in Jakarta with a performance built on defensive resilience and tactical discipline.
For Fukushima, the result also adds another Indonesia Open title to her career after winning the event in 2019.
Malaysia end long men’s doubles wait
The final match of the day brought more history, as Goh Sze Fei and Nur Izzuddin defeated Indonesia’s Raymond Indra and Nikolaus Joaquin 13-21, 21-18, 21-10 to win the men’s doubles title.
The Malaysian seventh seeds recovered from a slow start and then took control of the match as it wore on, ending an 18-year wait for a Malaysian men’s doubles title at the Indonesia Open. The last Malaysian pair to win the event were Mohd Zakry Abdul Latif and Mohd Fairuzizuan Mohd Tazari in 2008.
For Indra and Joaquin, the opening game was full of promise. Backed by the home crowd, they played with speed and confidence, taking it 21-13 and raising hopes of an Indonesian title on home soil.
But Goh and Izzuddin responded well. They tightened up the flat exchanges, reduced the attacking opportunities for the Indonesians, and took the second game 21-18 to force a decider. Once the match moved into the third, the Malaysians had the momentum and were far more clinical, pulling away to win 21-10.
It completed a strong week for Goh and Izzuddin, who had already beaten world number ones and reigning champions Seo Seung Jae and Kim Won Ho in the semifinals. Their title in Jakarta confirms their status as one of the leading men’s doubles pairs of the season.
For Indonesia, finals day brought more heartbreak. Christie fell short in men’s singles, and Indra and Joaquin were denied in men’s doubles, meaning the wait for a home winner at the Indonesia Open continues.
