Playing at the National Stadium in the first game, the Trinidadians put the game to bed at half-time when they led 3-0 after Aruba had a man sent off, and the Caribbean champions cruised in the second half to complete an easy victory for their first full points of the competition.
T&T were in front as early as the third minute when Aikim Andrews collected a long ball down the right and crossed for Mitchell to slot home from close range.
In the 16 minute, it was Andrews who got on the scoresheet to double T&T’s lead. Mitchell and Levi Garcia combined on a cleverly taken free kick and Andrews finished off with a simple tap in.
In the 30 minute, Joel Geerman was given his walking papers after taking down Andrews in the box, and Kadeen Corbin scored the resulting penalty.
Trinidad’s domination continued after the break when Duane Muckette smashed in a 30-yard volley to stretch the lead to 4-0, and Mitchell completed his brace when he scored from the spot after David Dubero tripped Garcia in the area.
Aruba’s consolation strike came in added time at the end courtesy Duncan Homoet. The goal was the country’s first at this level.
Jamaica, meanwhile, were left searching for their first win after they were felled by a Stheven Robles goal mid-way through the first half. Mauro Portillo sent a searching ball down the right and Robles collected, beating one defender with a lovely chip, before holding off another defender to hammer a right-footed shot past goalkeeper Nicholas Nelson.
Still down 1-0 at the break, Jamaica were then let off the hook in the second half as Guatemala wasted a handful of chances.
Portillo missed a 52 minute penalty and then shot over the crossbar in the 74minute while Mario Hernandez saw header saved from point blank range in the 64 , and watched as another shot flew wide later on.
In the other game played, Panama beat the United States 1-0.
