Skipper Dax McCarty gave the visitors an early lead after only three minutes before Bradley Wright-Phillips found the back of the net twice in quick succession at the end of the first half to increase their advantage to three.
The Englishman first headed home a cross from Mike Grella in the 42nd-minute and then netted with an acrobatic overhead kick just seconds before the interval after NYCFC’s defence failed to clear another of his fellow forward’s deliveries.
McCarty later grabbed his second six minutes after the restart before Wright-Phillips teed up substitute Alex Muyl just five minutes later for the Homegrown midfielder and New York native to grab his first MLS goal.
Gonzalo Veron and Gideon Baah went on to complete the scoring in the final 10 minutes as head coach Jesse Marsch described his side’s performance as “incredible” at the final whistle.
“Not in our wildest dreams would we have predicted 7-0,” he told newyorkedbulls.com after the game. “But I think it was again an expression of the belief and the commitment that this team has for each other and a chance for them to show mostly themselves what we’re all about.”
Wright-Phillips, who now has five goals in 13 games this season, added: “I can’t explain it. I’m still trying to think now. seven-nil is crazy, especially with the players they’ve got.
“We came in today and showed them nothing but respect, which is why we worked so hard, and today we were just so clinical and everything came off for us.”
After claiming the 2015 Supporters’ Shield title, the Red Bulls had been enduring a slow start to the 2016 campaign with six defeats in their opening seven games, but four victories from their last six matches has since got them back on track.
The club now sit fourth in the Eastern Conference on 16 points, one behind NYCFC, and have won all four meetings with their rivals since the two sides faced each other for the first time last season.
“You know, it’s been a weird year,” Marsch added. “We haven’t been able to show our quality at a lot of moments and we haven’t always played at our best, but the whole time that we were going through our struggles we just thought when we get out of this, we’re going to be better.
“So that’s been the focus, that’s been the concentration, and I think that you know again, after coming off a good year, there’s something to overcome with the complacency, but now with a tough start we just knocked some of that out and we’re trying to fill back in all the little details and the work ethic to get us back to where we can be.”
