Gray, making his second appearance for the Reggae Boyz, celebrated his 27th birthday in style when he scored his first goal as a Jamaican international in the 14th minute and added a second in the 28th minute.
The Everton winger’s second came after Leon Bailey (17th) doubled the lead, while Chelsea-bound rising sensation Dujuan Richards, who was an 82nd-minute substitute, capped the victory with his first senior team goal in the 90+2 minute. With that, the 17-year-old became the youngest ever goalscorer in Gold Cup history.
Trinidad and Tobago got what turned out to be a consolation through Andre Rampersad in the 49th minute.
The win –which was also Heimir Hallgrimsson’s first since taking the reins as Jamaica’s Head coach late last year –provisionally saw the Boyz to the top of the standing on four points, one ahead of Trinidad and Tobago.
Group favourites United States, on a point, were leading newcomers St Kitts and Nevis, without a point, 4-0 at half-time in the late kickoff.
The much-anticipated clash between Jamaica and Trinidad and Tobago
Was the first international men’s game to be played at the 22,000-plus capacity stadium and though it wasn’t the most attractive or entertaining encounter, the spectators that turned out were well treated to five goals.
It was initially projected to be a close contest, especially as the Soca Warriors Head coach Angus Eve opted for a defensive 5-4-1 formation that was expected to prove difficult for the Reggae Boyz to break down.
But it became clear early that the objective of the formation would prove futile, as Michail Antonio dispossessed a defender a played a cheeky pass off to send Bobby Reid on his way. However, Reid took an unwanted touch and later hit the ball in the side netting.
The Soca Warriors briefly enjoyed a good passage of possession where they looked threatening in open play but couldn't create any meaningful opportunity and later found themselves behind.
In the 14th minute, a decent build up by the Reggae Boyz ended with Bailey finding an unmarked Gray, who buried his right-footed effort in the left corner beyond the slightly advanced, Frenderup in goal for Trinidad and Tobago.
Bailey doubled the lead three minutes later when he timed his run to perfection to latch on to a long pass from Joel Latibeaudiere and finished with aplomb in a one-one-one situation with Frenderup. The goal was initially flagged as offside, but that decision was later overturned on by VAR.
The Soca Warriors tried to play their game but were hardly allowed any room to cause any problems for Jamaica’s defence and, as such, only absorbed consistent pressure.
They found themselves 3-0 down before the half-hour mark after Kevon Lambert won possession and found Antonio. The West Ham man then slipped by a defender and placed a pass on a platter for the wide-opened Gray to complete one of the easiest finishes of his career.
As the score remained unchanged at the break, the half-time team talk by Angus, coupled with Jamaica's defensive frailties, saw Trinidad pulling one back four minutes into the resumption.
Captain Levi Garcia got away from Jamaica’s debutant Dishon Bernard and drove a pass in for Rampersad to apply a back heel finish beyond Andre Blake, while under pressure from two defenders.
Still, the Jamaicans continued to apply consistent pressure and created numerous opportunities to add to their tally, but those were squandered due to both faulty shooting and poor decision-making.
It wasn’t until close to the end that they got another when Richards’s shot from a distance took a wicked deflection and sailed past the flat-footed Frenderup, who had no chance.
