"People always considered me a better player at team events. But, in individual competitions, I also always gave my utmost effort," Shi said during a mixed-zone interview after the final.

"This time, finally securing my first individual world championships title makes me so delighted, not necessarily having to prove anything to anyone. I just feel so relieved."

Once labeled by critics as a "big-time choker" for his collapse under pressure at previous high-stakes events, Shi broke his worlds hoodoo the hard way, saving two match points in his semifinal win over Canada's rising star Victor Lai, followed by an earlier, hard-fought third-round comeback win over Frenchman Christo Popov.

"I fought six matches in this tournament, each one incredibly tough. Many were matches I nearly lost, but managed to turn around. So, clinching it in the end felt incredibly rewarding," said Shi, who dictated play in the decider with his pinpoint smashes from deep to crack Vitidsarn's defense.

Shi's victory on Sunday put a Chinese name back on the men's singles honor roll, after the country had dominated the event by racking up eight straight wins from 2006-15 at the worlds, spearheaded by the legendary Lin "Super" Dan's five titles.

Standing 1.84 meters tall with long limbs and a quick footwork, Shi wields power, variety and finesse in his shots, and has been compared to the all-time greats, such as Lin and Chen, as the next leader of China's men since his international debut a decade ago.

A spell of misfortunes, including a serious left ankle injury in 2019 and two more on his right ankle and elbow, which required multiple surgeries to get him back in shape, took a heavy toll on his progression, mentally and physically.

Now, with the world title coming at a perfect time, CBA head Zhang expects greater things will come, continuing to pay back Shi's unremitting effort.

"Shi's been carrying a lot of weight and doubt all the way, even though he's done extremely well for us at all the team events," said Zhang. "Now that he's realized his dream (of winning an individual world title), I feel so happy for him, and I think we are yet to see his best."

Earlier in the women's final, Japan's fifth seed Akane Yamaguchi took just 37 minutes to beat China's injured former world No 1 Chen Yufei 21-9, 21-13 to add a third singles world title to her golds from 2021 and 2022.

Chen, women's singles champion at Tokyo 2020, battled past top seed and reigning champion An Se-young of South Korea in a semifinal win marred by a nasty-looking ankle twist early in the second game.

In the final, Chen appeared hampered in her movement and Yamaguchi took full advantage to close out a comfortable straight-games victory.

"Since last night I've been undergoing treatment. Before taking to the podium just now (to receive her medal), I'd already taken eight painkillers," said Chen.

Malaysian fourth seeds Chen Tang Jie and Toh Ee Wei claimed a dominant 21-15, 21-14 victory over second-seeded Chinese pair Jiang Zhenbang and Wei Yaxin in the mixed doubles final. The men's doubles crown went to Korean top seeds Kim Won-ho and Seo Seung-jae after their 21-17, 21-12 victory over China's Chen Boyang and Liu Yi.
