India archer Atanu Das hit the bull's eye in a one-arrow shoot-off to knock two-time Olympic champion Oh Jin Hyek out of the Tokyo Olympics and storm into the pre-quarter finals on Thursday.
It was the greatest win in the career of 29-year-old India number one, who was snubbed by the team's think tank and lost his place to rookie Pravin Jadhav in the mixed team event on Day 1 of the competition.
Returning to action after the humiliation, Das showed amazing resilience as he bounced back from being 2-4 down to edge out the Korean great by shooting a perfect 10 in the one-arrow shoot-off.
Oh had won the individual gold medal in London 2012 and was a member of the gold medal winning team at the ongoing Tokyo Games.
He was also part of the bronze-winning team at 2012 Olympics.
Das and his world number one wife Deepika Kumari are the two Indians left in the fray in archery .
Deepika has also made the round of 16.
Das saw off a tough challenge from Chinese Taipei's Deng Yu-Cheng earlier in the day.
Both the players won two sets each following some intense shooting and were tied 4-4. In the decider too they went neck-and-neck till 19-all.
But the archer from Chinese Taipei crumbled under pressure, misfiring a 7, as Das, who had slipped behind rookie Jadhav in the ranking round on Friday, held his nerve to seal a 6-4 victory after drilling in a 9 in the yellow-ring.
