G. Sathiyan pulled off a huge upset win over Sweden's Mattias Falck, a 2019 World championship finalist and the eighth seed, 8-11, 3-11, 11-6, 11-7, 11-6 win in the second round of the WTT Star Contender Doha here on Monday.

Sathiyan, world ranked 37, rallied from being 0-2 games down to script one of his best wins of his career. The Indian raced to a 6-2 and 9-2 lead before the Swede, ranked 17 in the world, won four points in a row. Sathiyan didn't relent as he took the last two points; one with a backhand block and the other a backhand winner.

"Extremely happy. Beating [Falck] for the first time. He's a tricky player with pimple on his forehand. This is certainly one of my best wins. Taking on Kristian Karlsson next will be tough," Sathiyan told Sportstar .
