"Playing with your feet and pulling off tricks on people. The most fun for me is trying to put the ball between people's legs," said Alexis.
She is hoping for a spot on her high school soccer team this fall. She encouraged other girls to follow in her footsteps.
"Girls aren't told they can do a lot of stuff. I feel bad, because it's not true," said Alexis.
Rebecca Webb of San Francisco woman came with her three-year-old daughter to watch the match.
She said showing girls early in life that they can do whatever they set their mind to is crucial to future success.
"She sees all these wonderful ladies out there playing. We watch a lot of football, [so it's] mostly boys football that she sees. So I think it's good for her to see it's not only boys who play," said Webb.
People came to watch the display of skills by female soccer players on the world stage and heard the advice of world class athletes.
"Fall in love with something. Try everything. You may not know soccer is your thing until you give it a try," said Heather Petri, who won gold as part of the 2012 U.S. Olympic Women's water polo team.
San Francisco will be hosting two other public viewings of Women's World Cup soccer matches at Civic Center Plaza on June 30th for a semifinal game and for the World Cup Final on July 5th. For more information visit the SF Rec and Park website.
