Quarter Finals: Spain beat Croatia modestly Lithuania beats China fairly easily USA beats Australia easily Greece beats Argentina barely
Semi-Finals
Spain beats Lithuania modestly USA gets crushed by Greece (just kidding, the US should win this, but you know who I will be rooting for)
Final USA beats Spain
Now these are all fairly conventional predictions except for Greece-Argentina where Argentina is favored so at least one will be wrong.
So far there have been few surprises. With the possible question of Australia, these are the best 8 teams in the world.
