FRISCO, United States (AFP) - The United States played to a goalless draw against Guatemala here Wednesday in a curtain-raiser to the teams' clash in the opening match in Group B in the CONCACAF Gold Cup in June.

The draw, in front of 10,932 fans, ended Bob Bradley's run of three straight victories as coach of the United States. It also ended Landon Donovans three-game goal-scoring streak, having scored five goals in the USAs opening three games of 2007.

"I think it was a good learning experience, particularly for our younger players," Bradley said. "Its a different kind of game, one that they need to see, because we all understand that we are going to see these kind of games in qualifying. At times tonight it seemed like we were afraid to make a mistake. We have to find the confidence to push the game harder."

Guatemalas best chance in the first half came on the stroke of halftime when explosive forward Carlos Ruiz's scissor-kick toward goal bounced over the crossbar.

The USA had a chance in the 61st minute, when Donovan put a ball into the area that was weakly cleared to a wide-open Jonathan Spector.

The West Ham defender tried to hammer an awkward shot on goal from 15 yards out, but couldnt connect with any force.

The best chance of the game for either team came moments later when Clint Dempsey put the ball through to Justin Mapp in the left side of the area, but Mapp blasted his low attempt wide of the right post.

The scoreless draw for the Americans came on the heels of a 3-1 victory over Ecuador on Sunday in Tampa, Florida, which featured a hat trick from Donovan.

The USA won't play again until they take on China on June 2 in San Jose, California.

Five days later, they launch their defence of the CONCACAF Gold Cup title. After the Gold Cup, which runs from June 6-24, the Americans will play by invitation in South America's Copa America.
