With just eight teams in the women’s water polo field, all teams were guaranteed a spot in the quarterfinals. U.S. center back K.K. Clark said the Rio Games are basically split into two different tournaments – and the second begins Monday with the semifinals.

“The next three matches are do or die, so we’re trying to distinguish them and play two tournaments,” Clark said after Saturday’s game against Hungary. “We’re happy with our performances but we know we can do better. The first tournament is over. We did well. We can’t get too happy because the next games are going to be way harder.”

The U.S. was the No. 1 seed in Group B, and continue their gold medal Monday in the first game of the semifinals at 1:10 p.m. ET against Brazil.

Here’s a look at the rest of the water polo quarterfinal matchups.

Game 1 – United States vs. Brazil, 1:10 p.m. ET

The United States (3-0) had no trouble in their first three games of group play, scoring 34 goals while only allowing 14. Brazil had the exact opposite problem, allowing 33 goals while only scoring 13 of their own.

The Americans are shooting 44 percent in the tournament. Captain Maggie Steffens leads the U.S. with 10 goals scored in 14 shots. Newcomer Maddie Musselman has also proved to be an offensive force, scoring eight goals on 15 shots.

Despite the scoring prowess, the U.S.’s key to victory has been their defense. Goalkeeper Ashleigh Johnson has saved 28 shots on 42 attempts for a 66 percent save percentage. The U.S. has also picked up 23 steals and 10 blocks in three games.

Brazil (0-3) has struggled in the Rio Games, coming away with just 13 goals in three games. Leading scorer Izabella Chiappini had six goals, including four in one game.
