WOMEN'S WATER POLO

The U.S. women, including backup goalie and Corona del Mar High product Tumua Anae, as well as assistant coach Dan Klatt from UC Irvine, defeated China, 7-6, Friday to close out Group A play.

Team USA finished tied atop the group with Spain (both 2-0-1), but lost the goal-differential tiebreaker and will be the No. 2 seed from Group A. The Americans lost a 9-6 lead in the final minutes of a 9-9 tie with Spain in their group clash.

This means that if the Americans can get past Italy (1-2 in Group B) in Sunday's quarterfinals, it would likely face Group A winner Australia, considered a gold-medal co-favorite with the U.S., in Tuesday's semifinals.

Australia (3-0 in group play) will face China (0-3) in the quarterfinals. Spain will meet Great Britain (0-3), while Russia (2-1) faces Hungary (1-2) to round out the quarterfinals.

Italy, the 2012 European champion, lost to Australia, 10-8, in group play. It also lost to Russia, 7-4.

The Americans rallied from a sluggish start against China, which held Team USA scoreless the first 11 minutes on its way to a 3-1 lead. China led, 3-2, at halftime, but suffered its own scoreless stretch of 14 minutes to allow the Americans to pull ahead and lead, 6-3, early in the fourth quarter.

Team USA scored all three third-quarter goals. The Americans were led by Maggie Steffens, who had three goals to give her 11 for the tournament. Four other U.S. players scored one goal apiece, while goalie Betsey Armstrong made six saves.
