All I have for now is that KC beat the San Diego Fusion 3-2 in the Quarter Finals. Their Semi Final opponent are the Tacoma Stars. Tacoma defeated Arizona 7-2.
Both KC and Tacoma went undefeated during the season(there were several teams that did so actually).
The other semi Final has Las Vegas who is also the host. LV lost 4 times during the season. They also lost a game in the first round before beating Santa Clara to make the QF round where they beat one of the favorites in Estadio Azteca.
Here is the latest update on the tournament.
