Twenty-year old Kyron McMaster of the British Virgin Islands produced the outstanding result of the meeting as he won the 400m hurdles in 47.80 – a national record that remained the fastest time run in 2017.
Jamaica’s Olympic 100m and 200m champion Elaine Thompson produced an impressive 200m victory on home soil in 22.09. That put her top of the early-season world lists in the longer sprint just a week after moving to the top of the 2017 times for the 100m following her 10.78 clocking at the IAAF Diamond League meeting in Shanghai.
Novlene Williams-Mills brought the home crowd to its feet with an emotional victory in the women’s 400m, clocking 50.54. The 35-year-old, who had operations for breast cancer in 2012 and 2013, had planned to retire at the end of the season.
“It feels good to come home and run a fantastic race one last time,” she said after her first win in the event in five years. “I think I’ve done enough for the past 10 years and it’s time to walk away.”
The men’s 200m was won by Canada’s triple Olympic medallist Andre De Grasse in 20.14.

The packed stadium of the Arena Caixa witnessed a superb display from Poland’s world and Olympic champion Anita Wlodarczyk, who began her IAAF Hammer Throw Challenge campaign with three throws beyond 75 metres, including a 78.00m winning effort. It extended the world record-holder’s winning run to 34.
Brazil's Olympic pole vault champion Thiago Braz da Silva failed to shine on his competitive return to home soil, having won in Rio with a South American record of 6.03m. Braz could only manage 5.40m and second place behind compatriot Augusto Dutra da Silva, who cleared 5.60m.
"We are confident that my results will be consistent soon," said the Olympic champion.

Ostrava, 27-28 June
A capacity crowd of more than 15,000 filled the Mestsky Stadium to mark Usain Bolt’s ninth and final appearance on the track – but on an evening of high emotion, the stand-out performer was Olympic 400m champion Wayde van Niekerk, who set a world best of 30.81 for the rarely-run 300m.
The South African’s effort surpassed not only Michael Johnson’s world mark of 30.85 from 2000 but also Bolt’s 30.97 meeting record.
“I’m just pleased and grateful for this big achievement,” said Van Niekerk, whose run came eight days after a 9.94 personal best in the 100m.
Bolt, who won the 100m in 10.06, commented: “It wasn’t a good race and I’m not happy with the time,” he said. But looking ahead to the IAAF World Championships, he added: “I’ll be fine.”
The meeting that had hosted Bolt most often in his career put on a farewell show for him which included a rendition of the Jamaican national anthem, celebratory music and fireworks.
Olympic triple jump champion Christian Taylor won in a meeting record of 17.57m.

Madrid, 14 July
Isaac Makwala became the first man in history to run a 200m within 20 seconds and a 400m within 44 seconds on the same day, winning both events in the Moratalaz Stadium on an evening when temperatures were close to 40C.
The sprinter from Botswana first won the 400m in 43.92.
“I’m satisfied, but I know I can run faster,” Makwala said in the 75-minute gap between events.
He then won the 200m in a personal best of 19.77, taking 0.19 off his best and breaking the meeting record of 19.92 set in 1987 by Carl Lewis. He also replaced world and Olympic 400m champion Wayde van Niekerk at the top of the season’s 200m list.
