The New York Red Bulls, Real Salt Lake and Chivas USA were all eliminated from the competition Saturday.
"As America is focused on the World Cup and the tremendous soccer happening in Brazil, tonight's results in the three NASL verse MLS matches show the strength and passion of the NASL clubs. We are very proud of the play on the pitch," said NASL Commissioner Bill Peterson. "We have three more matches next week, but this was a tremendous opening night of the U.S. Open Cup Fourth Round for our League."
