The winning margin was 2 cm which is the narrowest winning margin in the men's long jump at these championships.
Summary
Only four athletes were able to make the 8.15m automatic qualifier in the preliminary round. Wayne Pinnock's world leader 8.54 m (28 ft 0 in) and teammate Carey McLeod were the only two to make a qualifier on the first attempt. Every other jumper had to take all three attempts. It took exactly 8 metres to qualify, 7.99m did not make it.
It took 8 attempts in the first round before Thobias Montler achieved the first 8 metre jump and that was exactly 8.00m. The next jumper was Olympic Champion and returning silver medalist Miltiadis Tentoglou, who jumped 8.50m. Now the competition got serious. Next on the runway, Pinnock jumped 8.40m. At the end of the round, defending champion Wang Jianan did an 8.05m to move into third. The next jumper starting the second round, 2019 champion Tajay Gayle displaced Wang with an 8.17m. That lasted three jumpers until McLeod displaced him with an 8.27m. When Pinnock took his second attempt, it was also measured at 8.50m--a tie. The tie is broken with the second best attempt, so Pinnock's 8.40m put him in the lead. In the third round, Tentoglou jumped 8.39m, just one cm short of Pinnock's second best. And that was the way it would remain until the final attempts when Gayle's last attempt also was measured at 8.27m, another tie broken by his 8.17m. Suddenly off the podium, next on the runway, McLeod was only able to muster a 7.19m. Next up, Tentoglou hit 8.52 m (27 ft 11+1⁄4 in) to take the lead. As the leader coming in to the final round, Pinnock got last licks, but his 8.38m wasn't enough for the win. Jamaica took 2-4 places.
