Stanford grad Christen Press made an immediate impression in her World Cup debut, scoring the game winning goal.
Press scored in the 61st minute to snap a 1-1 tie and help the United States women's national soccer team open the Women's World Cup on a winning note Monday.
Team USA got two goals from Megan Rapinoe to beat Australia, 3-1, at Winnipeg Stadium in Winnipeg, Manitoba, Canada.
Rapinoe scored her 30th and 31st career goal with Team USA (8-1-2), becoming the 13th player with at least 30 goals and 30 assists.
She also became the 11th player to score a goal for the Americans this year. Abby Wambach leads with five goals.
Rapinoe became the first American women to record a multi-goal match in World Cup play in eight years.
It was her first goals at a World Cup since July 2, 2011, when she scored against Colombia.
The U.S. surrendered just its third goal in the past 10 games and has scored its opponents 23-3.
The Americans are 28-5-4 all-time in the Women's World Cup, outscoring their opponents, 101-33, in 37 games.
Team USA beat Australia for the second time in World Cup play, and the first since 1995.
Overall, the Americans hold a record of 23-0-2 against Australia, and have outscored them, 86-21, in a rivalry that dates to 1987.
Rapinoe opened the scoring after controlling a loose ball and taking a long-range shot that deflected off a defender's leg and found the back of the net.
The Matildas tied the match and took a 1-1 draw into the intermission.
Press gave USA the lead, getting an assist from Sydney Leroux, who dribbled down the side and found Press wide open in the box. She kept her poise and scored easily into the far corner.
Morgan Brian, Meghan Klingenberg, Julie Johnston, and Leroux joined Press in making their World Cup debut.
