HAMILTON, June 22 (Reuters) - Daryl Roberts and Stern John scored to give Trinidad and Tobago to a 2-0 win in Bermuda on Sunday which avoided an embarrassing early exit from the World Cup qualifiers.

Trinidad, attempting to reach their second successive World Cup finals, won the second preliminary round tie 3-2 on aggregate to reach the group stage of the CONCACAF qualifying tournament.

The Soca Warriors, under former Colombian coach Francisco Maturana, had slumped to a 2-1 home defeat against the part- timers in the first leg.

Bermuda coach Kenny Thompson was angry that John's goal, a 60th minute close-range header, was allowed to stand by Guatemalan referee Carlos Batres.

'We were making a substitution which put us at a disadvantage,' he told reporters.

Midfielder Kwame Steede was still making his way to the touchline to be replaced when the free kick from the left was pumped in.

'To our disbelief the Trinidad player has played the free kick in before our player has even entered the field,' Thompson said. 'Further to our disbelief the referee has allowed it. It was the difference between winning and not winning.'

Bermuda scarcely had a shot on goal as Trinidad tore into them from the start.

Roberts chested the ball down and turned to fire in a close-range shot at the near post and put the visitors ahead after 10 minutes.

Heroics from Bermuda keeper Timmy Figureido kept Trinidad at bay before halftime substitute John completed a convincing win.

In other matches, the United States won 1-0 in Barbados through a first-half goal from Eddie Lewis to complete an emphatic 9-0 aggregate win.

Haiti and Suriname also went through with away wins, Haiti beating Netherlands Antilles 1-0 after a goalless first leg and Suriname winning 2-1 away to South American neighbours Guyana for a 3-1 aggregate win.

Roberto Linhares scored a hat-trick for Cuba as they trounced Antigua and Barbuda 4-0 to go through 8-3.

El Salvador scored three times in the last 20 minutes to beat Panama 3-1 in San Salvador for a 3-2 aggregate win.

Jose Luis Garces doubled Panama's aggregate lead and gave them a precious away goal when he scored in the 14th minute.

Striker Eliseo Quintanilla scored twice, the second from a penalty, for El Salvador before Luis Anaya struck the decisive goal in the 87th minute.

Canada, Jamaica, Honduras, Costa Rica, Mexico and Guatemala had already qualified for the group stage.
