Incheon: Indian shuttler Parupalli Kashyap on Thursday advanced to the Korea Open men's singles quarterfinal after a three-game triumph over Malaysia's Daren Liew here.
Kashyap prevailed 21-17 11-21 21-12 in a contest that lasted 56 minutes.
He will next square off against the winner of the match between eighth-seeded Indonesian Anthony Sinisuka Ginting and Denmark's Jan O Jorgensen.
The 2014 Commonwealth Games gold-medallist is the lone Indian left in fray in BWF World Tour Super 500 tournament.
"In the first patch in the second game, he was playing really well. I was struggling and once he had a big lead, he played some very good shot. It was tough to make the scores equal.
"In the third game, I pushed the tempo and played a fast-paced game. I didn't give him a big lead."
On playing Jorgensen after a long gap, Kashyap said: "It would be a good match. He beat Ginting, so he is in good form. I don't know why he didn't play China Open. It will be a tough match. Let's see."
