Stanford grads Alix Klineman and Kristin (Richards) Hildebrand combined to produce 18 points and help the United States women's national volleyball team beat Argentina, 25-18, 25-18, 25-11, Wednesday night in the final match of group play at the Women's Pan American Cup.
The Americans finished 5-0 in their group to earn an extra day off at the event, which is a qualifier for the FINA World Grand Prix.
The U.S. advances to Saturday's semifinal round and will meet either Cuba or Brazil, depending on quarterfinal action that takes place Friday.
Cardinal grad Cassidy Lichtman and incoming Stanford freshman Haley Hodson each played briefly in the match, with Hodson recording a kill.
Klineman gained her points with six kills, three blocks and a service ace. Hildebrand had six kills and a team-high two aces.
Argentina finished third in group play and will meet Brazil in one quarterfinal match. Puerto Rico lost its first match to the U.S. and then won four straight to finish second and a meeting with Cuba.
The Dominican Republic, Pan American Cup defending champions, won Pool B and will play either Argentina or Puerto Rico on Saturday.
Team USA lost to the Dominican Republic in last year's championship match but has won two of the past three titles.
The U.S., Dominican Republic and Brazil each own three Cup titles, with Cuba leadfing the way with four titles. No other country has won the title since the Cup's inception in 2002.
