Apparently the U.S. men's volleyball team just needed to get all the jitters out.

Since losing six of seven sets to begin Olympic competition in Rio, the Americans have now won 12 of their last 14 sets, including a three-set sweep (25-23, 25-22, 25-20) of Poland Wednesday in the quarterfinals.

The American roster features eight first-time Olympians, including Stanford graduates Erik and Kawika Shoji, and the young group has gelled together to go 4-0 since the slow start.

Poland entered the Games as the No. 2 team in the world though it hadn't secured a medal in men's volleyball since the 1976 Olympics.
