Daley, a 10.08 performer at his best, recovered from a stumble at the start of his race to cruise home in 10.37 to win heat six.

Amidst the impressive performances, Michelle Smith from the US Virgin Islands stood out with her stellar run, setting the track ablaze with her speed and precision.

In the U17 Girls 400m hurdles, Nastassia Fletcher of Jamaica secured her second gold medal of the games with a time of 1:00.10. Despite strong competition from Darvinique Dean of the Bahamas, who finished in second place with a time of 1:00.66, and Jenna-Marie Thomas of Trinidad and Tobago, who claimed the bronze with a time of 1:01.03, Fletcher's determined effort propelled her to a commanding victory.

Meanwhile, in the U20 Girls 400m hurdles, Michelle Smith delivered a dominant performance, clocking an impressive time of 56.28 seconds.

In the Under 17 Boys 400m hurdles, Robert Miller of Jamaica made history with a remarkable performance, setting a new championship record with a time of 52.19 seconds.

While Jamaica's dominance was evident in three of the races, the Boys 400m Hurdles Under 20 saw a fierce battle between Jamaican athletes. Shamer Blake emerged victorious with a time of 51.21 seconds, closely followed by his compatriot Princewell Martin, who finished just behind with a time of 51.34 seconds. Dorian Charles of Trinidad and Tobago also delivered a commendable performance, securing the bronze medal with a time of 52.70 seconds.

Jamaica’s athletes swept the girls’ and boys’ Under-17 400m races, with the Under-20 events going to Guyana, as action continued on the opening day of the 51^st Carifta Games at the Kirani James Athletics Stadium in Grenada on Saturday.

Nastassia Fletcher of Jamaica finished tops in the girls’ Under-17 event, as compatriot Nickecoy Bramwell topped the boy’s Under-17 event in a championship record, while the impressive Guyanese duo of Tianna Springer and Malachi Austin were a cut above rivals in the Under-20 events.

Fletcher started the series with a tidy 54.32s-clocking to win the girls’ Under-17 event ahead of the fast-finishing Keyezra Thomas (54.59s) of Bahamas, with Antigua and Barbuda’s Tyra Fenton (54.89s) finishing third.

Bramwell then followed suit, as he successfully defended his boys’ Under-17 title. The smooth striding athlete had the field beaten from 200m out, but pushed himself to stop the clock in 47.27s, which lowered Usain Bolt’s 47.33s Championship Record set in 2002.

Kemron Mathlyn (47.96s) of Grenda and Eagan Neely (48.16s) of the Bahamas were the runners-up.

Meanwhile, Springer the Under-17 champion from last year, produced a breathtaking performance to top the girls’ Under-20 final in personal best 52.31s. She closed well to better the Jamaican pair of Abigail Campbell (52.85s) and Shaquane Williams (53.03s).

Austin, a Commonwealth Youth Games silver medallist, then brought the curtains down on the series, as he also produced a late charge to win in a new personal best 46.35s. He denied Jamaica’s Marcinho Rose (46.59s), with Joshiem Sylvester (46.93s) of Grenada in third.
