The men's singles top seed Viktor Axelsen of Denmark only struggled for a moment in the first game as he lost a four-point advantage to fall behind India's Sai Praneeth 19-18. But the Olympic champion pulled himself together soon to win the opening game 22-20 before nailing the second 21-11.

"It feels great to be back and to see all the fans back in the stands," Axelsen was quoted as saying by the tournament's official website. "I have great memories from here now, it's one of the biggest tournaments of the year and one of my biggest dreams coming true to win it. Hopefully I can try to do that one more time."
