BLG 2-0 TEC
This is the right one... I'd like to say that the 17G win against these guys on 11/03 was a fluke, and I really do think it is! AAAAY expressed his confidence in the player interviews, and said "if you want to watch an FPX match and you don't know which to watch, just book a ticket for the grand finals." Well, if he and FPX really want to get to the grand finals, I think a dominant 2-0 here would be ideal.
Anyways, skill-wise, FPX beats 17G. 2-0 FPX win.
