INCHEON, South Korea - South Korea's Kim Min-Jae won a shock silver medal in the men's 105kg weightlifting Friday and then melted hearts by cuddling his eight-month-old baby son on the victory podium.
Yang Zhe won China's sixth lifting gold with a total 403kg.
But that was only after two major medal chances crashed out leaving Kim (397kg) to celebrate the biggest upset of the week on the final day of lifting at the Moonlight Festival Gardens Arena.
Uzbekistan's Sardorbek Dusmurotov (391kg) claimed an equally unlikely bronze.
After the silver medal was placed around Kim's neck, baby Kim Myung-Jun was brought out from backstage to join the party and grabbed affectionately at his dad's shiny new trinket.
The crowd were then treated to the sight of the trio of giant heavyweight medallists cooing and playing with a smiling Myung-Jun on the podium as Kim held the baby in his arms.
Kim had no pedigree at this weight, having been Asian champion at 94kg in 2012, and on paper the gold looked destined for Iran's accomplished Olympic silver medallist Navab Nasirshelal.
But he inexplicably failed with all three second phase lifts, one at 217kg and twice at 219kg, and was eliminated to stunned silence from the large contingent of Iranian supporters.
Minutes earlier another big contender, Sergey Istomin of Kazakhstan, also failed three times at 211kg to leave the minor medal positions wide open.
"I didn't realistically expect to win a medal today because I'm not in the best shape at the moment," the 30-year-old Kim told AFP.
He added that the big jump from 94kg to 105kg had been a natural one.
"It was becoming a challenge to keep my weight at 94kg. I thought I could lift better at a higher weight class," Kim said.
Nasirshelal was too upset to speak after, but his angry coach said he was at a loss to explain what had happened.
"Navab could lift 220kg two hundred times in training but I don't know what happened today," Bahman Zare told AFP.
"This was a big chance for gold today. I'm not pleased." Yang, with the pressure off after his great rivals' departure, duly put in a lift of 217kg to take gold on a total of 403kg, far short of any Games or Asian records.
Hhe failed with subsequent efforts of 221kg and a final Games record attempt of 230kg.
"Once my rivals had gone out I lost some motivation and I couldn't get fired up to make those last two lifts," Yang said. "If they had mattered, well, of course, it would have been a different story."
