A couple of sweeps started the day for the men's volleyball quarterfinals Wednesday with Russia and the U.S. advancing.
The four winners will square off against each other in the semifinals Friday.
Russia gets a shot to defend its title
The Russian men's volleyball team took home the gold at the 2012 Olympics in London and they'll get an opportunity to do so again at the Rio Games.
The stage looked too big and the brights too light for the upstart Canadians as Russia easily rolled past them in straight sets.
That pits Russia against Brazil in the semifinals. The winner will go on to the gold medal game while the loser will play for bronze.
U.S. in cruise control now
The United States men's volleyball team has won four matches in a row after dropping the first two (which included a sweep at the hands of Canada in the Olympic opener).
Poland - the No. 2 team in the world - became the Americans' latest victim, losing in three sets to end any hopes of taking home a medal.
The U.S. will take on the winner of Italy in the semifinals Friday.
Italy keeps rolling
The No. 4 team in the world may need a higher ranking.
After another dominant performance Wednesday in the quarterfinal sweep over Iran, Italy is a lock for one of the top four spots in the Rio tournament and may be the gold medal favorite the way it's playing.
Italy moved to 5-1 in Rio, with the only loss coming to Canada in a meaningless match (for the Italians, at least) at the end of prelims.
Brazil narrowly escapes Argentina
The Brazilian men's volleyball team did what the women's team could not: Advanced beyond the quarterfinals.
As the dominant women's team wiltered in the face of adversity Tuesday night, the Brazilian men fought off a tough Argentina team to earn a trip to the semifinals and guaranteed two more indoor volleyball games for the host crowd to cheer for.
Brazil moves on to face the defending gold medalists (Russia) in the semifinals.
