But there were shocks in the men’s long jump, where London 2012 finalist Marquise Goodwin, who heads this year’s world lists with 8.45 metres, Mike Hartfield, who is third in the 2016 lists with 8.34m, and world indoor champion Marquis Dendy all failed to qualify in a thrilling competition won with a leap of 8.59m by Jeffery Henderson that was aided by a twist of luck - a following wind of 2.9 metres per second,  0.9 above the limit for record purposes.

For Dendy the process was particularly galling as he was beaten to the third and last qualifying place by London 2012 bronze medallist Will Claye after both men had reached 8.42m.

The 23-year-old Dendy, who registered his best effort in the third round, fouled his next jump and was unable to continue any further, which meant that the 25-year-old Claye, who also won a silver medal in the London 2012 triple jump, earned his spot thanks to a superior second best jump of 8.38m as compared with Dendy’s only other effort, 7.75m.

The surprise package of the event was Jarrion Lawson, who was second, just a centimetre shy of  Henderson.

Gatlin won the men’s 100m final in 9.80sec, with 20-year-old Bromell - who took the bronze medal to the older athlete’s silver behind Usain Bolt at last year’s International Association of Athletics Federations World Championships, claimed his first Olympic place in 9.84.

Marvin Bracy was the third qualifier in 9.98.

Tyson Gay, the 2007 world 100 and 200m champion, could only manage fifth place in 10.03.

Before the final Bromell, who has the same agent as Bolt, said he was confident the 29-year-old world record holder - who pulled out of the Jamaican trials final with hamstring problem yesterday after running 10.04 in the semi-final - would be able to defend the 100 and 200m titles he has won at the last two Olympics.

“He’ll be back,” said Bromell. 

“I know he’ll bounce back.”

Felix, whose  activities have been undermined by an ankle injury in a season where she hopes to defend her Olympic 200m and challenge for the 400m, earned the right to contest the longer distance at Rio 2016 as she won in 49.68 ahead of Phyllis Francis, who clocked 49.94, and Natasha Hastings, who recorded 50.17 in a race which saw 2014 world indoor champion and London 2012 4x400m relay gold medallist Francena McCorory miss the cut back in fifth place in 50.37.

English Gardner won a hugely competitive women’s 100m title in 10.74, the second fastest in the world this year behind the 10.70 run by Elaine Thompson in winning the Jamaican trials on Friday (July 1).

Tianna Bartoletta took second place in 10.74, with Tori Bowie claiming the third qualifying spot after clocking the same time.

LaShawn Merritt, the 30-year-old 2008 Olympic champion and 2013 world champion who served a two-year doping ban in 2009, won the men’s 400m final in 43.97 ahead of Gil Roberts, in 44.73, and David Verburg, in 44.82.

Chaunte Lowe won the women’s high jump as she cleared 2.01m, with Vashti Cunningham - daughter of former NFL quarterback Randall Cunningham - taking the second spot with a best of 1.97m, and Inika McPherson finishing third with 1.93m.

Olympic champion Ashton Eaton was a runaway winner in the decathlon with a total of 8,750 points.
