Creighton All-American Norah Sis had 13 kills as the U.S. under-21 volleyball team won its Pan American Cup pool with a 3-1 victory over Argentina last night. 

In a matchup of teams that came in with 2-0 records in Mexico, the Americans won 25-16, 25-21, 22-25, 27-25.  Two Huskers also contributed to the win.  Freshman Bekka Allick had two kills, five blocks and one ace serve, while libero Lexi Rodriguez had 19 digs. 

The victory earned the U.S. a bye into the semifinals, which begin tomorrow evening with the time and opponent TBA.
