China's Wang Yifu, who collapsed after a blunder cost him an Olympic gold on Saturday, was out of medals and on oxygen again when he returned to the shooting range in the 50-meter free pistol event.
But Roberto Di Donna, the Italian who took advantage of Wang's astonishing error to win the air pistol event, himself wilted under pressure Tuesday and allowed Boris Kokorev to claim Russia's third shooting gold of the Games.
Wang's collapse on Saturday, when he needed an oxygen mask and medical assistance, provided one of the most dramatic images of the Olympics.
He finished sixth Tuesday. Chinese officials said he was still suffering from dizziness and headaches that had also affected him before the Games. He again used an oxygen mask at the conclusion of the event.
