Three Bermuda swimmers stormed through their heats into Saturday night's finals at the Central American and Caribbean Age Group Championships in Havana, Cuba.

And the Island was represented in another four finals last night as some of Bermuda's top competitors continued to lower their personal best times.

In a meet which began on Friday and has attracted some 600 swimmers, including a number of Olympians and a short course world champion, Bermuda's squad have so far impressed.

Stephen Fahy, who narrowly failed to qualify for last year's Atlanta Olympics, has twice lowered his personal best in the 100 metres freestyle. In the men's 18-21 age group heats he clocked 54.29 seconds and then in Saturday's final brought that time down to 54.27 to place sixth.

Trevor Nelson, who like Fahy represented Bermuda at the last Commonwealth Games, dropped two seconds off his best time in the 15-17 100 metres breaststroke, clocking 1:08.81 to qualify for the final.

But he couldn't repeat that performance in the final, finishing eighth in 1:09.18.

Saturday's other Bermuda finalist was Alicia Mullan who took eighth place in the 400 metres individual medley in 5:28.29.

Meanwhile, last night Fahy, Mullan, Stephen Troake and the freestyle relay team of Nelson, Troake, Matt Hammond and Ronald Cowen were all due to swim in finals.

Troake swam the second heat of the 15-17 100m freestyle in a personal best of 54.35, improving his time by almost a second. And Fahy qualified for his second final -- the 100m butterfly -- with the sixth fastest time of 58.45 in the heats. The fastest time belonged to Francisco Sanchez of Columbia, winner at the world short course championships in both the 500 and 100m freestyle.

Mullan was scheduled to go in the final of the 200m breaststroke, seeded sixth in her age group.

Others to have recorded personal bests without reaching the final include: Tamika Williams (18-21 100m free 1:03.16); Graham Smith (13-14 100m breast 1:14.00); Jessica Marwick (13-14m breast 1:26.65); Paul Fox (13-14 100m free 57.83) and Jimmy Pereira (13-14 100m free 59.23).

According to Bermuda Amateur Swimming Association official Colleen Nelson, who is travelling with the Bermuda squad, the Games are the most competitive ever for the region with Cuba, Mexico, Venezuela and Columbia all represented by large teams. In all some 23 countries are competing.

Besides Sanchez, also taking part are Cuba's Neisser Bent, Olympic bronze medallist in Atlanta last year and in the world short course championships in the 100m backstroke, and Leah Martindale of Barbados who's ranked in the world's top ten in the 50m free.

The meet continues through Friday.
