In fact, India scooped up three titles out of the five events in the tournament.
Top seed Sindhu, who has been in rampaging form last season, brushed aside Indonesia's Gregoria Mariska in the summit clash, while Sameer, who had reached the finals of Hong Kong Super Series, defeated compatriot B Sai Praneeth 21-19 21-16 in a 44-minute final.
Second seeds Pranaav Jerry Chopra and N Sikki Reddy, who had won Grand Prix titles at Brazil and Russia, also lay claim to their maiden GPG title in mixed doubles after beating compatriots Ashwini Ponnappa and B Sumeeth Reddy, seventh seeds, 22-20 21-10 in the finals.
The girl from Hyderabad led right from the start and never allowed her younger opponent to pose any threat. She entered the break at 11-5 and 11-6 in the first and second games respectively and never looked back.

In the end, it was a couple of returns going to net from the Indonesian which sealed the issue for Sindhu.
Sameer, on the other hand, fought back from 5-11 down in both the games to outwit fellow Indian Praneeth, who looked slightly in discomfort with his right shoulder and also committed too many unforced errors to hand over the match, despite earning early leads.
In the second game, Praneeth once again zoomed to a 6-3 lead after Sameer kept hitting the shuttle out.
The Madhya Pradesh shuttler tried to gather a couple of points at his opponent's forecourt but he committed a few unforced errors and Praneeth also dominated the net play to move into the break at 11-5 advantage.
However, just like in the opening game, Sameer once again scripted a comeback and levelled the scores when his rival hit wide. He then produced a cross court smash to take the lead.
