The triumph ensured she capped off the season that saw her take giant strides in the sport, on a positive note.
"We are extremely happy. This year has been good for Sindhu. She received Arjuna award, bronze in world championship. Now, this win at the end of the year makes us happy," Sindhu's father P V Ramana told PTI here.
He hoped Sindhu would do well in the big tournaments like Asian Games, Super Series among others scheduled for next year.
Sindhu continued to take giant strides towards asserting herself as the rising star of Indian badminton by lifting the Macau Open Grand Prix Gold title with a thumping win over Canada's Michelle Li in the summit clash in today.
The top-seeded 18-year-old won the match 21-15 21-12 in merely 37 minutes to clinch her second Grand Prix Gold title after the Malaysia Open in May.
The Indian sensation, who was bestowed the Arjuna award this year, was ruthlessly dominant from start to finish in the lop-sided encounter against the seventh-seeded Canadian.
