The Trinidad and Tobago swimmers solidified their lead at the top of the overall team standings after the completion of night three of the 17th biennial Caribbean Islands Swimming Championships at the National Stadium Olympic-size pool in Kingston, Jamaica Sunday.

And the T&T Male 15 and Under and Female 17 and Under water polo teams claimed their division titles Sunday with big wins over Jamaica and the Netherland Antilles.

Trinidad and Tobago currently have 627 points, a lead of 124.5 points over second placed Jamaica (502.5 points), while Puerto Rico are third on 421.

In swimming, T&T grabbed 21 more medals (7 gold, 5 silver and 10 bronze) on the third day to compile an overall 57 medals (18 gold, 19 silver, 21 bronze) with two more days remaining in the regional age-group competition--last night and today.

T&T Olympic female qualifier Sharntelle McLean led the charge Sunday with two gold medals in her pet event, the 50-metre freestyle, and the 50m backstroke in the Girls 18 & Over division.

McLean showed her Olympic qualification, achieved at the Bahamas National Swimming Championships last month, was no fluke when she again dipped under the Olympic B standard in the event (26.32 seconds) with a 26.27-second effort in a race in which her teammate Kimba Collymore was fourth in 27.40 seconds.

In the 50-metre backstroke, McLean led a one-two punch for T&T with Donna Marie-Wickham, beating her countrywoman to the wall 31.15 to 31.38.

Trinidad and Tobago also turned two good shots at gold in the sport's blue riband event, the 50m free for Girls and Boys 15-17, into reality when Cherelle Thompson (26.89) and Caryl Blondell (24.11) justified their position as favourites.

Then T&T's outstanding 11-12 Boys duo of Keegan Boisson and Joshua Romany each secured a gold.

Boisson tied the 2004 CISC record of 30.83 seconds established by Suriname's Allard Tjon Lim Sang, just pipping Romany, who posted a 30.86-second swim.

And Romany swam a commanding race in the 200-metre free to easily take gold in 2:06.57.

In the 100m fly, Boisson grabbed bronze (1:03.83), while Romany was fourth (1:04.27).

The other gold came from 2008 FINA World Youth Swimming Championships campaigner Christian Homer in the 50m back when he touched the pad in 27.85 seconds. Cadell Lyons (28.68) earned the bronze there.

Earlier, T&T's Stefan Sharpe secured the bronze medal in the Boys 13-14 1500m free in a personal best, by nearly 20 seconds, of 17:41.56

Strasser Sankar (24.22) and Jarryd Gregoire (24.57) were silver and bronze medallists, respectively, in the Boys 18 & Over 50m free.

Gregoire (28.70) also splashed to bronze in the 50m back for that age-group.

Those were the same medals won by Chloe McMillan (32.60) and Brittany Stewart (33.15) in the Girls 15-17 50m back.

Kristen Julien recorded another personal best in the 50-metre backstroke (33.56) to capture bronze in the Girls 11-12 50m back.

And Kadeja Phillip (1:20.68) stroked her way to bronze in in the Girls 13-14 100m breaststroke, while her compatriot Rejan Chin was fifth in 1:20.94.

In the two 800-metre freestyle relays for the Girls and Boys 15-17, T&T were third and second, respectively.

In CISC water polo action, the T&T Female U-17 team defeated the Netherland Antilles 10-3, while the Boys Under-15s swamped Jamaica 19-7 to lift their respective crowns.

And the T&T Male U-17 squad battled to a 7-7 draw with the Dominican Republic to maintain this country's overall unbeaten record in this competition to date.

Last night, T&T swimmers and water polo players were expected to pile up more wins and more medals, a situation they hope to replicate today, final day of the meet.
