Williams, 19, who set a new national U20 record of 11.01 on Sunday, clocked a new personal best of 10.98, despite a poor start to record her second win in as many days.
Mikiah Brisco finished second in 11.09 with Dezerea Bryant finishing third in 11.14.
Williams had given a hint of what to expect in the preliminary round when she ran 10.97 to win her heat. However, the trailing wind of 2.5m/s prevented that time from being recognized as the Jamaican national U20 record.
In the final, the wind was only 1.0 m/s well below the allowable limit of 2.0m/s.
Earlier, Yohan Blake was second in the 100m clocking 10.09s as he trailed the USA’s Ronnie Baker across the line. The American clocked 9.99.
Marvin Bracy-William was third in 10.11.
Williams wasn’t the only Jamaican with a new personal best Monday night, as promising sprint hurdler Britanny Anderson clocked 12.59 to win the 100m hurdles. It was almost a duplicate of the 12.58 lifetime best she ran in the preliminary round, except for the poor start in the final where she defeated Christina Clemons, who clocked 12.64 for second place narrowly edging 2015 World Champion Danielle Williams who ran 12.65 for third.
Earlier, Javon Francis won his 400m race in 45.84. Quintaveon Poole was second in 45.87 and Myles Pringle third in 46.11.
The BVI’s Ashley Kelly won her 400m in 54.86 over Belize’s Samantha Dirks 55.01 and Canada's Carline Muir 55.48.
Shamier Little won the 400m hurdles in a world-leading 53.12 beating Jamaica’s Ronda Whyte, who ran a season-best 54.33 for the runner-up spot. Her compatriot Shiann Salmon, also ran a personal best of 54.97 for third.
Peters, the reigning world champion, broke his own national record on his opening throw of 88.96m but lost the lead when Jakub Vadlejch hurled the javelin out to a new world lead of 89.87m in the fourth round.
Spurred by the challenge, Peters uncorked his first ever 90m throw in the penultimate round, hitting a new personal best of 90.19m only to see Vadlejch surpass him once more with a personal best of 90.88m.
Undaunted the Grenadian, who once wanted to be a sprinter, flung his best-ever throw, 93.07m to put victory beyond Vadlejch’s reach. It was a new national record and personal best for Peters, and the fifth-best throw in history.
Meanwhile, Ricketts, the 2019 World Championships silver medalist produced a winning mark of 14.82m in challenging conditions caused by blustery winds as high as 6.5m/s that aided her winning jump.
Ukraine’s Maryna Bekh-Romanchuck took second place with her best effort of 14.73, her fourth jump of the competition that was helped by a gale force wind of 6.3m/s.
Dominica’s Theo LaFond took the final podium spot with her fourth-round jump of 14.43m assisted by a 3.6m/s wind.
Miller-Uibo last lost a 400m on this track back in 2019 when Bahrain’s Salwa Eid Nasser stunned the world with a 48.14 run at the World Championships. This time it was the Dominican Republic’s Marileidy Paulino, the Tokyo Olympics silver medallist who stormed home in a season-best 51.20.
Stephenie-Ann McPherson trailed the imperious but clearly winded Bahamian up until the last few metres before overtaking her to clock a season-best 51.69. Miller-Uibo trudged across the line in 51.84 for third.
Barbados’ record holder Sada Williams (52.09) and Tokyo Olympic finalist Candice McLeod (52.37) finished fourth and fifth, respectively.
Shericka Jackson, who won the 100m at the National Stadium in Kingston last weekend, lost her first race of the outdoor season clocking 22.07 in the 200m after getting caught late by the USA’s Gabby Thomas, who ran a season-best 21.98 that equalled the meet record set by Allyson Felix back in 2015.
Dina Asher-Smith, the reigning world champion, clocked a smart 22.37 in her 200m opener, which was good enough for third place.
There was a blanket finish in the 100m hurdles that Kendra Harrison won in 12.43 but can count herself lucky to win. Brittany Anderson led off the last hurdle but appeared to stumble and faded to third in 12.44, the same time awarded to Nigeria Tobi Amusan who was awarded second place.
Bahamas’ Devyne Charlton was some distance back running 12.61 for fourth place while Megan Tapper hit the first hurdle and finished eighth in 12.92.
The 400m hurdles offered a glimpse of what to expect in the event this year as Alison Dos Santos, the Tokyo Olympics bronze medallist out-paced silver medallist Rai Benjamin down the home stretch to win in a world-leading 47.24, which was also a new meet record.
Benjamin was timed in 47.49.
The rest of the field was far behind but Thomas Barr of Ireland was the next best running 49.67 for third while Kyron McMaster finished fourth in 49.93.
Jaheel Hyde was fifth in 50.23.
Prior to her season opener one week before where she ran a windy 12.47, Camacho-Quinn's last hurdles race had been in 2019 and the Rio 2016 Olympian had started questioning whether her future lay in competing over the barriers.
But her perseverance is paying off and in Gainesville the two-time NCAA champion took 0.08 off her own Puerto Rican record, which had been set in 2018, to make a statement in Olympic year.
Behind her, British sisters Tiffany Porter and Cindy Sember both clocked 12.62, with Brittany Anderson finishing fourth in 12.91.
In the men's 110m hurdles, USA's world 60m hurdles record-holder Grant Holloway – who clocked a wind-assisted 13.04 (2.2m/s) a week earlier – ran a world-leading 13.07 (1.3m/s) for a dominant win. Trey Cunningham was second in a PB of 13.28.
World 400m champion Steven Gardiner went quickest over one lap, clocking 44.71 in his first 400m race since his world title win in Doha in 2019, as Britain’s Matthew Hudson-Smith was second in 45.53. Fastest in the women’s events was Jessica Beard with a time of 51.00.
Javianne Oliver won the women’s 100m from Olympic long jump champion Tianna Bartoletta – 11.12 to 11.16 (2.2m/s).
The men’s 100m saw the quickest time come in the university race as Jo'Vaughn Martin improved his PB from 10.40 to 9.94 (1.6m/s) to equal the world lead. Justin Gatlin went quickest in the 'Olympic Development' races with 9.98 (1.4m/s) ahead of Andre De Grasse with 9.99, Kenny Bednarek with 10.03 and Noah Lyles with 10.08.
Just one week after clocking 10.72 for 100m, Sha'Carri Richardson continued her fine form to run 22.11 (1.0m/s) in her 200m season debut on the first day of Tom Jones Memorial Invitational action on Friday (16).
It is the 21-year-old’s second quickest ever time for the distance behind her PB of 22.00 set in Florida last August and saw the world U20 record-holder win the heat by almost half a second ahead of Lynna Irby with 22.57.
World and Olympic medallist Blessing Okagbare was third in 22.66.
The time clocked by Richardson – who moved to sixth on the world all-time list with her 100m run the week before – is the second-fastest in the world at this early point of the season behind Shaunae Miller-Uibo’s 22.03 from earlier this month.
World 400m bronze medallist Fred Kerley went quickest in the men’s 200m heats, equalling his PB with 20.24 (0.9m/s) ahead of Jereem Richards with 20.30. Erriyon Knighton won another heat in 20.39 (0.5m/s).
World 400m hurdles silver medallist Sydney McLaughlin improved her 100m hurdles PB to 12.92 (0.2m/s) at the Bryan Clay Invitational in Azusa, California, on Friday (16).
With that result, the 21-year-old becomes the first woman to break 13.00 for the 100m hurdles, 23.00 for 200m and 53.00 for the 400m hurdles.
She was back in action just 40 minutes later and ran 51.16 in the 400m heats.
The peerless Bahamian ran a world-leading 49.08s to win the one-lap event at the USATF Grand Prix, Oregon Relays in Eugene, destroying a quality field in the process. It was easy then to understand her joy.
“God, I thank you. Opened up with a 400 this weekend 49.08, second fastest opener and fourth fastest time,” she said on Instagram.
“Shout out to my training partner for also running her fastest season opener this week,” she said in reference to Gordon-Powell’s winning 50.84-second run at the 2021 LSU Alumni Gold meet held at the Bernie Moore Stadium in Baton Rouge, Louisiana.
Miller-Uibo continued: “We’re in a good place and I am excited to see how the rest of the season goes. Now it’s back to training.”
The Bahamian, whose winning time was a meet record and facility record, and Trinidad and Tobago’s Jereem Richards, were the only two Caribbean athletes who won in Eugene.
She was completely dominant in the race in which the USA’s Lynna Irby finished in second place in 50.28 while Jessica Beard was third 50.38.
Richards was also in good form in the Men’s 200m that he won in a season-best 20.26.
The USA’s Josephus Lyles 20.46 to finish second.
Both were metres clear of Jamaica’s Christopher Taylor, who ran a season-best 20.73 for third.
Trayvon Bromell won the Men’s event in 10.01 over Noah Lyles 10.17 and Liberia’s Emmanuel Matadi 10.19.
Jasmine Camacho-Quinn won the women’s 100m hurdles in 12.46, finishing ahead of Jamaica’s Britanny Anderson, who ran a season-best 12.82 and Taliyah Brooks of the United States who clocked 12.83.
Donald Scott of the United States won the Men’s triple jump over Jamaica’s Clive Pullen and many time global champion, Christian Taylor. Scott jumped 16.89m while Pullen got a season-best 16.55m. Taylor was third with 16.52m.
The Women’s shot put was badly affected by rain that caused some of the throwers to slip and fall. However, it ended with the USA’s Chase Ealey winning with a mark of 18.93m. Jamaica’s Danniel Thomas-Dodd put 18.46 for second place.
Jessica Ramsay of the United States threw 18.40m for third.
