Looks to me it is not a freak result.
His team is simply better than you. Look at his stats...4 wins and a draw in 5 matches. You don't get that kind of run if the team is mediocre. This is not a freak result. It is definitely a case of the better team winning. Being higher in quality does not necessarily mean you are the better team by the way.

I've learned in T11 that having supporters around will help a bit, but it does not mean you will win. Accept the result and move on.
