ESCHEN, LIECHTENSTEIN, MAY 30 -- The World Cup-bound U.S. soccer team posted an easy 4-1 exhibition victory over Liechtenstein's part-time squad today.

It was the next-to-last warm-up before the U.S. team faces Czechoslovakia June 10 in the first round of the Cup.

"We just want to polish our game, that's all," U.S. Coach Bob Gansler said.

The match was tied at 1 before the United States broke open the game with second-half goals by Marcelo Balboa, Eric Wynalda and Chris Henderson. The win improved the U.S. team's record in its exhibition matches leading up to the World Cup to 6-6. The team will meet Switzerland Saturday in its final practice match.

Gansler experimented today, rotating the attack after halftime, with Tab Ramos and Paul Caligiuri being rested.

Peter Vermes opened the scoring for the United States in the 10th minute, kicking in a hard volley from 20 meters. Liechtenstein tied the score in the next minute on an effort by Donath Marxer, a low shot that beat goalie Kasey Keller.

Midfielder Balboa put the United States ahead in the 53rd minute with a header off a Paul Krumpe cross. Second-half substitute Wynalda made it 3-1 after 66 minutes. Henderson slipped in the fourth goal in the 75th minute.
