Stanford incoming freshman Jordan Raney scored three goals and the United States youth women's water polo team beat Mexico, 25-2, on Saturday to earn a spot in Monday's semifinal round of the UANA Junior Pan American Championship at the Riverside Aquatics Complex.
The American youth men's team tied Brazil, 7-7, early Saturday and then beat Argentina, 18-6 later in the day.
The U.S., with Menlo School senior Nicholas Bisconti serving as team captain, plays Mexico on Sunday to complete pool play.
The U.S. women's team completed pool play unbeaten in four matches. Raney has scored nine goals in the tournament, which also includes a 21-1 win over Puerto Rico, a 10-4 win over Canada and a 19-4 win over Brazil.
Bisconti has three goals through five matches and the American men are 5-0-1, tied with Brazil, with one match remaining. The U.S. has an aggregate score of 94-33, while Brazil has outscored its foes 83-39.
Stanford junior Laura Liedle and sophomores Jane Campbell and Stephanie Amack may miss the Cardinal's first two games of the season and coach Paul Ratcliffe is fine with that.
Should the trio not be able to join Stanford in a weekend series against North Carolina and Duke, it means they will be playing for the FIFA U-20 Women's World Cup championship scheduled for the same weekend in Canada.
Duke and North Carolina will also be missing players for the same reason.
The Stanford trio is currently part of a 27-player pool at training camp through July 23 in Seattle, a camp designed to help select the final 21 players who will take on Germany on Aug. 5 in Edmonton, the Cup's first day of competition.
Stanford's season opens on Aug. 22 against the Tar Heels, with a game against the Blue Devils on Aug. 24.
