Bajrang Punia's perennial leg-defence weakness came to haunt him at the big stage as he lost the men's freestyle 65kg semi-final to three-time world champion Haji Aliev at the Tokyo Olympics on Friday.
The Indian wrestler will fight for the bronze medal on Saturday.
Rio Olympics bronze-winner Aliev of Azerbaijan consistently attacked Bajrang's legs and twice got himself into position from where he could roll the Indian comfortably for easy two-point throws.
Trailing 1-4 after the first period, Bajrang looked for a big attack but Aliev very smartly effected a counter take down, placing his shoulder close to the thighs of Bajrang and threw the Indian for a huge 8-1 lead.
The Azerbaijani was losing steam and Bajrang got two take-downs to reduce the deficit but the required big move never came. Under 30 seconds left in the bout, Bajrang desperately looked for an attack but Aliev did not let him do that by gripping him in strong body-lock.
A dejected and helpless Bajrang fell on the mat, aware that he had lost battle to a superior wrestler.
If he manages to win the bronze, India will match its best result at the Olympics. Sushil Kumar and Yogeshwar Dutt had won a silver and a bronze at the 2012 London Games.
Ravi Dahiya had claimed the silver medal in the 57kg event on Thursday.
Bajrang began the day by edging past Kyrgyzstan's Ernazar Akmataliev and then pinned Iran's Morteza Cheka Ghiasi to reach the semis.
Bajrang trailed the Iranian for a major part of the bout after being severely crippled by Ghiasi's defensive tactics, especially the body-locks.
Twice, Bajrang was put on activity clock and also left to defend his right leg when Ghiasi got hold of it.
As the second period moved towards the final minute, Ghiasi looked like making a dangerous move when he got hold of Bajrang's right leg and almost pulled off a take down.
Bajrang not only wriggled out of that clutch, but also locked the neck of Ghiasi and moved into a position from where he turned his rival, pushed him on the mat and held him with his immense strength to emerge victorious by fall.
Just before the end of the first period, Bajrang was 3-1 ahead but Akmataliev ran the Indian close in the second period, getting two push-out points to level the scores.
Since Bajrang had the high scoring move, a two-pointer take down, he was declared winner on criteria.
It was not the most clean and fluent victories that he is known for, but was just enough for Bajrang, who came into the Games after suffering a minor knee injury during a local Russian tournament.
Debutant Indian wrestler Seema Bisla could not find a way to get out of the defensive trap of Tunisia's Sarra Hamdi and lost her 50kg opening round 1-3.
The 27-year-old could not make her moves as Hamdi applied the body lock to great effect, never allowing Seema to initiate a strong attack.
There were hardly any moves in the bout with Hamdi getting two of her three points on push out and one on Seema's passivity.
Seema got on board when she too pushed her rival out after being put on activity clock for a second time.
The Tunisian later lost her next bout, which drew curtains on Seema's campaign.
The Rohtak grappler had not even won a national event till 2017 but went on to secure her berth for the Games by winning the World Olympic Qualifier, held in Sofia in May.
