Who was the winner of Summer Slam? Hard to say, Erik and the
Mauler come very close.
The Mauler played 7 games averaging 66.7 points.
Erik played 5 games averaging 65.0 points.
Father played 4 games averaging 50.0 points.
Punisher played 4 games averaging 39.6 points.

In those 5 matches where Erik and the Mauler directly played
each other, Erik defeated the Mauler twice; and Matt defeated
Erik twice. But the straw breaker is that Erik only garnered two
first place finishes, while the Mauler captured 3 first place
finishes in those 5 matches.

So it would have to be decided that The Mauler is the champion
of the first ever Summer Slam!
