Sai Praneeth stunned sixth seed Anthony Sinisuka Ginting to go through to the quarter-finals of the BWF World Championships in Basel, Switzerland.
He is the only Indian shuttler remaining in the men's singles after HS Prannoy and Kidambi Srikanth were knocked out on Thursday.
Sai brought his 'A' game to court with the Indonesian unable to respond to his precise smashes and intricate play.
The first game saw both players on the front foot with Sai taking advantage of a couple of lax backhands to move closer in and bombard his opponent with smashes.
The efforts paid off as he took a tight first game 21-19.
The 16th seed started the second game strongly but Ginting came roaring back, showing flashes of inspiration to take an 11-8 lead at the mid-game interval.
But that was as good as it got for Ginting as Sai dominated with his powerful smashes after the break, taking 13 of the next 15 points to take the match 21-19, 21-13.
Next up for Sai is a last-eight encounter with another Indonesian, Jonatan Christie.
Prannoy falls to the best
HS Prannoy could not repeat the heroics of his second-round victory over two-time Olympic gold medallist Lin Dan as he went out in straight games to defending champion Kento Momota.
Prannoy fought valiantly in the first game against Japan's world number one, playing several long rallies and matching his opponent move for move.
But the 24-year-old showed his class to take the opening game 21-19 and kept control after that.
Momota's sharpness, speed and decision-making was too much for Prannoy as he took the second game 21-12 to set up a quarter-final clash with Malaysia’s Lee Zii Jia.
Srikanth falls
Srikanth Kidambi made a disappointing exit in round three in Basel, falling in straight games to Thailand's Kantaphon Wangcharoen.
Seventh seed Srikanth was forced to dig deep in his second-round win over Israel's Misha Zilberman, and he looked jaded from the start of the contest.
Wangcharoen led 11-6 at the first mid-game interval and took the opener 21-14 with Srikanth well short of his all-action best.
The second game was a similar story with the 12th seed completing a 21-14, 21-13 victory in just 40 minutes.
Sindhu sensational
PV Sindhu was close to her brilliant best as she dispatched USA's Beiwen Zhang in straight games to reach the quarter-finals.
The runner-up at the last two World Championships and the Olympic Games was 5-2 down early on but five points in a row saw her turn the match on its head.
She went on to take the first game 21-14 and was simply irresistible in the second, her combination of deft drop shots and fierce smashes proving far too much for the ninth seed.
Sindhu won 21-14, 21-6 in just 34 minutes and now meets her old rival, Chinese Taipei's second seed Tai Tzu Ying, in the last eight.
