New York Red Bulls had Felipe Martins sent off just past the hour mark, six minutes after Diego Fagundez broke the deadlock.
The New England Revolution claimed their first win of the MLS season thanks to a 1-0 victory at home to New York Red Bulls on Friday, but it was not without controversy.
After three draws and a loss to the start the season, the Revolution finally opened their account thanks to Diego Fagundez's 55th-minute effort at Gillette Stadium.
Felipe Martins was shown a straight red card six minutes later for a seemingly innocuous challenge in midfield and the Red Bulls lost their way from that point as they slumped to a third defeat in four matches.
