Momota and Sindhu faced little opposition in their final matches on Sunday. The Japanese defended his title in style, with a crushing straight sets victory over Denmark's Anders Antonsen 21-9. 21-3.
In a rematch of the 2017 world championship final, Olympic silver medallist Sindhu dismantled Japan's Nozomi Okuhara 21-7, 21-7 to clinch a long-awaited maiden global crown.
The world number one made quick work of fifth seed Antonsen, needing only 37 minutes to seal his second title.
Momota's form at the tournament was certainly reflected in the scorelines.
The 24-year-old breezed through to the title without dropping a single game, and his 21-9, 21-3 thumping of the Dane set a record for the best ever winning score at a World Championship final.
“I came here wanting to win and I had the confidence that I would do well. I trained a lot for this. This competition was always on my mind. I played at a consistently high level.” - Kento Momota
Sindhu's golden moment
Meanwhile PV Sindhu has won India's first badminton world title in spectacular fashion.
It was the most one-sided women's singles final since the 21-point game was introduced in 2006.
"I’m so happy. I was expecting this for a long time. It’s definitely a proud moment for me and for India. A lot of people have been waiting.” - PV Sindhu
Sindhu suffered heartbreak as she went down to her Japanese rival in an epic 2017 final in Glasgow which lasted an hour and 50 minutes, the second-longest women's singles match in history.
This was a very different match.
The 24-year-old raced into an 8-1 lead with Okuhara appearing to be feeling the effects of her tough semi-final win over Ratchanok Intanon.
She clinched the first game 21-7 and the second game followed the same script.
Okuhara was chasing shadows and, while her game at the net was up to its usual high standard, she just could not trouble the Indian with her shots from the deep.
Sindhu opened up a 16-4 lead in the second game and would not be denied this time around as she made it third time lucky in world finals.
After 38 minutes, it was all over with the Hyderabad native raising her hands after finally securing the title her talent deserved.
“This is my answer to the people who have asked me questions over and over. I just wanted to answer with my racket and with this win – that’s all.” - PV Sindhu
Best birthday gift
Sindhu's historic feat was the perfect gift for her mother who also celebrated her birthday on Sunday.
"I dedicate this medal to my mother it is her birthday" - PV Sindhu to The Times of India
Sindhu's gold medal in Basel takes her tally of world championship medals to five, equaling the record of legendary Chinese player Zhang Ning.
