The United States have won their fourth World Baseball Softball Confederation Under-18 World Cup title in a row after beating South Korea in the final in Thunder Bay today.

The Americans eased to the gold medal after thrashing the Koreans 8-0 in the gold medal match at the Port Arthur Stadium.

Neither side could make it onto the scoreboard in the opening stages and the match remained pointless after the second innings.

The US soon showed their superior quality though and had all but wrapped up the title after the fourth innings.

Three runs in the third and four in the fourth handed them a 7-0 advantage.

Another single in the fifth inflicted further misery on South Korea, who could not score a single point of their own as the US ran out comfortable winners.

The tournament continues to be dominated by the US, who were also winners at Seoul in 2012, Taichung in 2013 and, most recently, in Osaka two years ago.

"The credit goes to our under-18 programme," said US manager Andrew Stankiewicz.

"It is so well organised.

"The talent has always been there, but in the past we didn’t show this ability to put it together.

"Our greatest success has been creating a team spirit.

"We knew that we had talented players, but we were not sure we could have a great team on the field."
