Notable Semifinal matches in US Open Cup history
The very first Semifinal round of the US Open Cup (then called the National Challenge Cup) saw a pair of Brooklyn teams reach the Final. On April 18, the Brooklyn Field Club, which finished first in the National Association Football League, defeated New Bedford FC 2-1, on two goals by Hall of Famer Robert Millar, after Beckton had given the New Englanders a 1-0 lead. Both teams played much of the game with ten men each, after Clark of Brooklyn and Chadwick of New Bedford were sent off in the 35th minute for fighting.
