Belarusian Ivan Litvinovich has edged Chinese veteran Dong Dong to win gold in the men's trampoline in Tokyo while Australia's Dominic Clarke had an unhappy Olympic final.

Making his Olympic debut Clarke had the fourth-best score in qualification but bounced out mid-routine in the final to fall to the bottom of the field.

Young Kiwi Dylan Schmidt won a surprise bronze medal.

Dong looked set to collect his fourth Olympic medal - and second gold - with Litvinovich bouncing perilously close to the edge of the mat during his routine.

But Litvinovich, the top qualifier, benefited from his superior difficulty and flight time to score 61.715 and just pip Dong's 61.235.

Dong, 32, previously won gold in London, silver in Rio and bronze in Beijing back in 2008.

Defending Olympic champion Belarusian Uladzislau Hancharou finished fourth.

China's Gao Lei, winner of the last four world titles, did not even make it to the finals after crashing onto the mat.

Clarke, 24, advanced to the eight-man final with a combined total of 111.680, scoring 52.130 in his first outing and cracking a wide smile after nailing a 59.550 in his second routine.
