Jamaica swept the podium in all four 4x100 metres relay races as the country topped the medals table for a 35th consecutive year at the Caribbean Free Trade Association (CARIFTA) Games in the Cayman Islands.
The Jamaican team finished the event at Truman Bodden Sports Complex with 85 medals, including 36 gold, 33 silver and 16 bronze.
The haul was three more than Jamaica claimed at last year's Games in the Bahamas.
Crystal Shaw, Brianna Lyston, Glacian Loutin and Kay-Lagay Clarke won the women's under-17 4x100m event in 45.63sec.
Trinidad and Tobago earned silver and Bermuda took bronze.
Briana Williams, winner of the sprint double over 100m and 200m, then led the women's under-20 squad to 4x100m gold.
Williams, Joanne Reid, Ackera Nugent and Kemba Nelson clocked 44.23 to finish ahead of Trinidad and Tobago, while Barbados claimed bronze.
Richard Nelson, Adrian Kerr, Christopher Scott and Nkrumie Bouwahgie secured the men's under-17 4x100m relay title in 41.59.

The Jamaican quartet were too quick for the rest of the field as The Bahamas were second in 42.18 and Trinidad and Tobago sealed bronze in 42.45.
Ryiem Robertson, silver medallist in the 100m, anchored Jamaica to gold in the last 4x100m relay, the men's under-20 race.
Oblique Seville, 100m champion, Vashaun Vascianna and 200m gold medallist Xavier Nairne set Robertson up for victory but he was forced to fend off The Bahamas before crossing in a combined 39.46.
The Bahamas and Barbados claimed silver and bronze, respectively.
International Association of Athletics Federations (IAAF) President Sebastian Coe was among those in attendance on the final day.
Coe announced the CARIFTA Games, the Inter-Secondary Schools' Boys' and Girls' Championships and Jamaica as the latest recipients of the IAAF World Athletics Heritage Plaque.
"Many congratulations to the Jamaican schools and CARIFTA Games, your historic contribution to the development of athletics is unquestionable," said Coe.
