Scoring early and often, the United States men's junior national water polo team swamped Mexico, 15-6, in Riverside on Sunday to clinch a spot in the semifinal round of the UANA Junior Pan American Championships.
The semifinal winners play Tuesday for the gold medal, while the losers will meet to determine the bronze medal.
Menlo School senior Nick Bisconti, a center for the Americans, helped the U.S. control the tempo in building leads of 5-1 and 7-2.
Bennett Williams and Thomas Dunstan, a Connecticut resident who has appeared with the senior national team, each recorded three goals to lead Team USA.
The American junior women's team, with incoming Stanford freshman Jordan Raney, finished pool play unbeaten in four matches and will take on Puerto Rico in one semifinal. Canada and Brazil, each with matching 3-1 records, meet in the other semifinal.
