The win kept India’s challenge alive at the BWF Super 300 tournament as the other five Indian badminton players and doubles teams taking part on the day failed to cross the round of 16.
Praneeth, a world championships bronze medallist, saved a game point in the first game and a match point in the third game to defeat Jeon Hyeok Jin 24-22, 7-21, 22-20 in one hour and 18 minutes.
The world No. 49 Indian shuttler led Jeon Hyeok Jin by three points at the break and thwarted a late comeback by his opponent in the first game to take a 1-0 lead. Jeon, who is 65th in the badminton world rankings, turned the tables on Praneeth in the second game to restore parity.
The Indian then mounted a comeback in the third game to lead the South Korean shuttler 13-9 at one stage. However, Jeon Hyeok Jin drew level at 16-16 and had the match point opportunity at 20-19.
Praneeth, a former world 10, then scored three back-to-back points to set up a clash against Youth Olympic Games champion Li Shi Feng of China in the quarter-finals.
