World U20 champion Tina Clayton ran a national U20 record to win the women’s 100m title at the Jamaican U20 Championships in Kingston.

The 17-year-old registered her first sub-11-second clocking to supplant Briana Williams as the Jamaican U20 record-holder and climb to fifth on the world U20 all-time list after clocking 10.96 (1.0m/s).

“It’s a great feeling getting a new personal best,” said Clayton, whose previous best was the 11.09 that landed her the world U20 title in Nairobi, last year.

“This just motivates me to continue training hard, be disciplined and listen to my coach.”

In another thrilling final, as athletes target August’s World Athletics U20 Championships Cali 22, Sandrey Davison secured back-to-back domestic U20 titles when he made a strong rally through the last 40 metres to win the men’s equivalent in 10.20 (0.7m/s), a personal best.

“I almost fell coming out of the blocks while trying to get my drive phase correct,” said the world U20 4x100m silver medallist. “But I regrouped quickly and told myself that I’m going to finish strong and be victorious.”

Bouwahjgie Nkrumie, who dominated most of the race before Davison overtook him at the finish line, registered a personal best of 10.22. Davison duly completed the sprint double two days later, running a lifetime best of 20.84 in the 200m (-0.1 m/s). Roshawn Clarke solidified his status as Jamaica’s best one-lap after blitzing the field to win the event
