Tina Charles scored 18 points and Maya Moore added 16 to help the U.S. beat Australia 82-70 on Saturday night in the semifinals of the women's world championship.

The U.S. will face Spain in the gold-medal game Sunday. Spain beat host Turkey 66-56 for its first trip to the championship game. The Spanish team won a bronze medal at the 2010 worlds.

The Americans had to work hard for this victory — as is usually the case when these powers in women's basketball meet. The U.S. won its first four games of the tournament by an average of almost 48 points but couldn't put pesky Australia away until the fourth quarter.

Up 61-55 early in the fourth, the U.S. went on a 15-2 run, with Charles scoring six points in the burst to seal the outcome.
