With 17.15m the automatic qualifier, only 18 year old world leader Jaydon Hibbert was able to muster such a distance, his 17.70m far outdistanced that requirement.
Two jumpers later, Hibbert came down the runway but aborted his jump after hitting the take off board.
Two more jumpers, returning silver medalist Hugues Fabrice Zango hit a 17.37m to take a big lead.
Towards the end of the round, Fang Yaoqing jumped 16.89m, to move into second place, only to be displaced by Yasser Triki with a 16.96m.
Near the end of the fifth round, Zango broke that up with what turned out to be the winner 17.64 m (57 ft 10+1⁄4 in) as none of the leaders could improve enough with their final attempts.
