She and N Sikki Reddy were edged by Denmark by a whisker in their women's doubles match on Monday.
Denmark's match with India was filled with Olympic quality and all the medallists won their contests.
And finally the in-form duo of Ashwini/Sikki Reddy made it 4-1 with their fantastic win over Della Haris/Rosyita Putri Sari 21-12, 21-19.
Starting the proceedings, the new pair of Satwiksairaj and Ashwini produced another gritty performance to eke out a 22-20, 17-21, 21-19, over Tontowi Ahmad and Gloria Emanuelle Widjaja in a mixed doubles match that lasted 66 minutes.
Pusarla Sindhu, who took home silver at Rio previous year, showed her class as she swept aside Line Kjaersfeldt in the women's singles to earn a consolation for India, while women's doubles runners-up Pedersen and Kamilla Rytter Juhl had to come from behind to beat Ponnappa and N. Sikki Reddy 18-21, 21-15, 23-21.
Denmark (6-4) topped the group, followed by India (5-5) and Indonesia (4-6) after the completion of the league stage.
In what will be a tough opening test, India, led by Rio Olympic silver medallist PV Sindhu, have to punch above their weight if they are to stand a chance against the two-time runners-up. Satwiksairaj and Chirag Shetty were literally dazzled by the virtuosity of the World's No 1 ranked Indonesian pairing of Marcus Fernaldi Gideon and Kevin Sanjaya Sukamuljo in the first game, but gave a better account of themselves in the second, to lose at 9-21, 17-21. India could have notched an unprecedented 3-2 tie triumph over the Danes, who incidentally are the reigning Thomas Cup men's team champions. Kidambi Srikanth raised the hopes of India in the men's singles, defeating Jonatan Christie in straight games.
Viktor Axelsen eased past Ajay Jayaram in 27 minutes in the men's singles and the men's doubles went Denmark's way soon after.
India had managed to reach the knockout stage of the tournament only once during the 2011 edition, while in the last two editions they couldn't even cross the group stage. Scoreboard.com provided the latest Group 1 standings.
