London Olympics bronze-medallist Saina Nehwal stormed into the women's singles quarterfinals of the Malaysia Masters badminton tournament with a straight-game win over South Korea's An Se Young here on Thursday.
The unseeded Indian, who had won the Indonesia Masters last year before going through a rough patch, dispatched Young 25-23 21-12 after a thrilling 39-minute contest.
This is Saina's first win over the South Korean, who got the better of the Indian in the quarterfinals of the French Open last year.
The two-time Commonwealth Games champion will next take on Olympic champion Carolina Marin in the quarterfinals.
Saina had defeated Lianne Tan of Belgium 21-15 21-17 in the opening round on Wednesday.
