Ocean City Nor'Easters are national Cupset specialists. Per Josh Hakala - founder of TheCup.us, the most comprehensive coverage of US Open Cup history to be found on the internet - the Nor'Easters' record of five upsets of professional opposition in USOC matches is bettered by only two other amateur teams, Des Moines Menace (seven upsets) and Michigan Bucks (nine wins over pro opponents).
The Nor'Easters were founded as the South Jersey Barons in 1996, but the Cupsets didn't start coming until 2005, when the team advanced to the third round of USOC with a 4-0 win over Long Island Rough Riders, and subsequently fell to Richmond Kickers, 8-4.
