The world No.11 overcame a much lower ranked Qin Jinjing of China 21-13 18-21, 21-19 in their first-ever encounter.
Sindhu took an hour and eight minutes to win the match and will take on world No. 30 and seventh seed Li Michelle of Canada in the title clash tomorrow.
Sindhu, who won the Malaysia Open Grand Prix Gold in May, has a great chance to bag another Tier-III title before the season ends next month.
