Battlegrounds: Second place without ever playing against first place?

I came second place without ever being matched against the first place player. First place was tier one, had no minions and only showed two matches in history, in both of these he won and made 55(!) damage against the same player.

If I knew how to attach files to this post I would share my screenshots.
