Grip strength, throwing distances achieved, average height etc etc - there are many advantages that the average man has over the average woman in disc golf (and javelin, discus, shot putt etc).
The man they reference in the article was playing for three years and is, reportedly, not particularly good in terms of his form.
He beat the reigning top female professional (16 years experience and acknowledged as the best female player by some margin) in 5 straight tournaments.
They play for money. Not a lot of money, compared to other pro sports, but enough to be able to pay the bills. By competing, he took money out of the pocket of every female player who ranked behind him.
Such a stunning and brave individual.
