The 25-year-old Bailey, younger brother of Olympic and World Champion Veronica Campbell-Brown, produced a career-best 44.43 to chase down Grenadian Olympic and World Champion, Kirani James, who had about a five-meter lead over Bailey heading into the final 100m of the race.

Moving to the 100m, Ackeem Blake produced a big personal best 9.89 to get a win over Americans Cravont Charleston (9.91) and Christian Coleman (9.91).
American Morolake Akinosun capitalized on the absence of both Sha’Carri Richardson and Marie- Josee Ta Lou from the Women’s equivalent to win in 10.97 ahead of countrywoman Melissa Jefferson (11.07) and Jamaican Junior Alana Reid (11.08).
In the field, 2019 World Championships silver medallist, Danniel Thomas-Dodd, produced a new personal best and national record 19.77m for third in the Women’s shot put. The event was won by the USA’s Maggie Ewen in a personal best and world leading 20.45m ahead of her teammate, Chase Ealy (19.98m).

The 19-year-old rising star ran a season-best 11.09 in the preliminaries of the 100m and then came back to ruin 11.15 to finish third in the final that was won by the outstanding American Sha Carri Richardson, who clocked 10.77, her third time under 10.8 in as many races this season.
With tired legs, Williams then ran the 200m finishing eighth in 22.96 in the race won by American Gabby Thomas in 22.12, the second-fastest time in the world this year. Allyson Felix ran 22.26 for second place in her season-opener.
Afterwards, Williams let her fans know how she felt about the day’s work.
“What a great day. Feeling like myself again,” she posted on Facebook. “Coach challenged me to run three races in two hours and it went (mostly) well.
“100m heats - an easing-up 11.09 one of my fastest-ever times in just 100m race number two since 2019. 100m final - third place 11.15 into a headwind. 200m final - (22.96w and dead last no legs left ?) but the work was necessary after no indoor season and working around an early-year injury.”
Williams has had a limited number of outings this season. She opened up outdoors with an 11.28 100m at the USATF Grand Prix in Eugene, Oregon on April 24. On that occasion, she just missed out on advancing to the final of the 100m that was won by Nigeria’s Blessing Okagbare in a season-best 10.97.
"On August 10, 2020, we welcomed the birth of our baby boy, Jaysha King Nieto. My world has now been made complete with this precious gift from God and the most amazing husband and now father @jamienieto," Shevon posted on her Facebook page late Thursday night.
Nieto, 37, represented Jamaica in the 400m hurdles at the 2004 Olympics in Athens, Greece and at the 2008 Games in Beijing, China.
Shevon Stoddart married USA high jumper Jamie Nieto in 2017. Jamie suffered a spinal injury in 2016 which left him paralyzed.
Earlier this year, Nieto, who is now pursuing a career as a singer entered the talent show America's Got Talent singing her song Through the Good and the Bad, that was dedicated to her husband. Her performance was praised by the judges including the world-famous Simon Cowell. She was four months' pregnant at the time.
However, she eventually withdrew from the competition after concerns over the spread of the COVID-19 virus caused a delay in production as well as concern for the safety of her unborn child.
"After the first round, which was pretty amazing. It was one of the best moments of my life. I was definitely looking forward to the next round. Even though Covid was there we waited to see what would happen, but when we realized that the virus was getting worse...the producers, they knew that that would be a concern. They wanted to make sure that I was also safe and I was also comfortable. It was bitter-sweet. I really appreciate the opportunity to being on the show."
The 30-year-old Trinidadian bested the field that included Americans Morolake Akinosun, who ran 10.98 for second place in the race aided by a legal wind of 2.0 m/s. Twanisha Terry, who ran 10.94 for victory at the Pure Athletics Global Invitational on May 1, finished third in 11.01.
This was the second time this season that Ahye has gone below 11 seconds in the 100m. She ran 10.96 for a third-place finish in her heat at the USATF Golden Games on April 16. She did not finish the final.
Tristan James of Dominica was also among the winners at the meet, jumping 7.86m to win the long jump competition. In what was a close battle, James emerged the victor over Kemonie Briggs, whose best of 7.81 secured second place while Dhanushka Piyarathne of Sri Lanka’s 7.76m leap earned him third place.
The oft-injured Javon Francis made a rare appearance in the 400m where he finished third in 46.09 behind the winner Tyler Terry 45.51 and Paul Dedewo (45.72).
Quarter-miler Roneisha McGregor was also third in the women’s 200m in a wind-assisted 23.18 (3.2m/s). Akinosun won the race in 22.67 with Lauren Rain Williams-James second in 22.83.
Smikle produced a consistent series with his two best throws coming in the first and sixth rounds.
The first round saw him produce a 65.26m, which would have been good enough to win, before five rounds later he threw the discus 67.07m.
Dacres, the 2019 World Championship silver medallist, was in third after four rounds with a best throw of 63.30m. After a foul in the fifth round, he produced a 64.51m effort in the final round to secure second place.
Samoa’s Alex Rose was third with a best throw of 64.03m.
