The Semifinals begin tonight with OrlandoCitySC hosting ATLUTD. Combined with tomorrow's MNUFC / TimbersFC game, this marks just the 10th time in US Open Cup history that all four semifinalists were all trying to make the championship game for the first time. We take a look back at the previous nine times that happened. Each one represents a different era of American soccer history. A history lesson from TheCup.us' Chuck Nolan Jr. >> bit.ly/2YKntrf #soccer #soccerhistory soccerhof #MNUFC #ATLUTD #VamosOrlando #RCTID TimbersArmy #MLS
