Competing in their first international event of the year, both the Indian swimmers also won gold medals in their respective events.
Sandeep clocked a meet record time of 1:02.45s in 100m breaststroke, while Supriya dished out a National record breaking performance of 2:00.54s in 200m butterfly.
The talented duo currently train under Dronacharya Awardee coach Nihar Ameen at Dolphin Aquatics in Bangalore and will feature next at the 2016 Japan Open Swimming Championship scheduled to be held in Tokyo between May 20-22.
Speaking after the event, an elated Nihar Ameen said, "The success of both Sandeep and Supriya is a testament to their dedication to practice and the commitment towards putting their best foot forward at every training session. Having surpassed the 'B' mark our next aim is to secure 'A' mark and ensure direct qualification to the 2016 Olympics."
