FORT COLLINS, Colo. (AP) _ The United States used strong serving and equally impressive passing to beat the combined Korean national team 26-24, 23-25, 25-15, 25-23 at Moby Arena on Wednesday night.

It was the U.S. team's fourth victory in its five-match tour with the Korean team, which represents North and South Korea. The U.S. team qualified for the Sydney Olympics in January at the Continental Cup in Canada.

``I believe Korea is as good as any team in the world (at) passing and we outpassed them,'' U.S. coach Doug Beal said. ``I think we served so much better than they did and did again in this match.''

John Hayden, who had 12 kills, and Phil Eatherton, who had 10 for the match, set the tone in the first game. Each had three kills, with Eatherton accounting for the final two points.

Korea came back to tie the match in Game 2, as Se-Jin Kim had three blocks for points.

Andy Witt had six of his 12 kills for the match in the third game, one the United States never trailed after taking a 2-1 lead. Game 4 was tied at 23-23, but the United States earned a point on Jin-Sik Shin's return error. Captain Lloy Ball closed the match with a winner off a feed from Hayden.

``We have been working hard to find a three-man block as often as we can and I thought it was pretty good tonight,'' Beal said. ``I wish everything we work on in the gym is as good when we play international matches.''
