Winters scored on a left-footed shot from 30 yards out that hit the crossbar and bounced into the net. Noyola, who will attend Stanford in the fall, cut past a defender, took a dribble and then slotted her shot from 10 yards into the lower right corner for her second goal in as many games.
The U-20s are preparing for the CONCACAF U-20 women's qualifying tournament that will send three teams to the 2008 FIFA U-17 Women's World Cup to be held this fall in Chile. Dates and venues for the qualifying tournament have yet to be announced.
Former women's national team coach Tony DiCicco is coaching the U-20s in his first tournament since being appointed.
"I am very pleased with six points after two games," said DiCicco. "For most of the first half, we played inspired soccer, but a two-goal lead is never secure internationally and especially when playing against Norway. The win gives us the chance to play host Chile for the championship in front of a full house and on national TV, which should be great for our players. I was especially pleased with the play of Keelin Winters. She was the difference today for the USA."
