On Tuesday, the two semifinal matches took place in the women's water polo event at the 2012 Summer Olympics in London. Both were close contests, but the gold-medal final has now been set. Spain defeated Hungary 10-9 on Tuesday afternoon and will face off against the United States on Thursday for the top prize.

Anni Espar Llaquet spurred her team on to victory. The Spanish player scored four goals in the game and helped Spain take a 10-7 lead into the final four minutes. Hungary made a last-ditch effort by scoring two late goals, but were unable to tie.

Regardless of which nation emerges victorious in Thursday's gold medal match, it will be a first. Neither Spain nor the U.S. has ever won the gold medal in women's water polo since the sport was added to the Summer Games in 2000. The United States won the silver medal in 2000 and 2008 and took the bronze in 2004. They have guaranteed that they will at least medal for the fourth straight Olympiad.

Thursday's gold medal game will begin at 3 p.m. ET.
