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.
The 21-year-old American ran 10.74 in the preliminary round of the 100m and then followed up with 10.77 in the final despite a stiff enough headwind of -1.2m/s. This is the third time in as many races this season that she has run under 10.8s.
Williams, who opened her 100m season with 11.29 in Oregon a week ago, clocked 11.15 for third in the final to follow up on her season-best 11.09 that she ran in the preliminaries for second in Richardson’s heat.
Javaine Oliver was third in 11.08.
McMaster broke his own British Virgin Islands national record of 47.54 when he clocked 47.50 for second place in the 400m hurdles won by Rai Benjamin in a world-leading 47.13. Alison Dos Santos, who finished third, also set a Brazilian national record of 47.68.
Jamaica’s Kemar Mowatt was fourth in a season-best 48.90.
Meanwhile, Kimberly Williams won the triple jump with 14.62m.
Thomas-Dodd threw 18.91m to finish second in the shot put won by the USA’s Maggie Ewen who threw a season-best 19.32. The USA’s Jessica Ramsay was third with her best effort of 18.58m. Two other Caribbean athletes finished in the top 10. Jamaica’s Lloydrica Cameron produced a personal best throw of 18.33m for sixth place while Trinidad and Tobago’s Portious Warren uncorked a 17.83m effort for eighth.
The 100m hurdles was keenly a contested race but world-record holder Kendra Harrison proved to be too much for the field running a season-best 12.48 for the victory. In her wake was Cindy Semper who ran a personal best 12.53 for second place. Nigeria’s Tobi Amusan clocked 12.61 for third, the same time as Devynne Charlton, who established a new Bahamas national record.
A couple of Trinidadian’s picked up third-place finishes in their respective events. Deon Lendore ran a season-best 45.04 in the 400m won by the USA’s Michael Norman in 44.40. Michael Cherry ran 44.86 for second place.
Meanwhile, Jereem Richards ran a season-best 20.20 to finish behind Noah Lyles and Kenny Bednarek, who ran 19.90 and 19.94 for first and second, respectively.
Gabby Thomas won the 200m in a season-best 22.12 over Allyson Felix who opened with a fast 22.26 for second place. Lynna Irby was third in 22.37.
Thompson-Herah ran the time in the heats but didn’t take part in the final later that day.
Olympic gold medallist in the 4x100m relay Briana Williams was also fast in the heats with a time of 10.91 before eventually finishing fifth in the final with 10.97 with an illegal 3.3 m/s tailwind.
The USA’s Twanisha Terry ran 10.77 to win the final ahead of teammates Aleia Hobbs (10.80) and Gabby Thomas (10.86).
