Brooks Koepka dominates PGA Championship with fifth major win.

Brooks Koepka's victory at the PGA Championship marked the first major championship win by a LIV Golf League player, validating the league's ability to compete at the highest level, according to members of the Saudi Arabian-financed circuit. Koepka's win, his fifth major title, was celebrated by LIV Golf CEO and commissioner Greg Norman, who congratulated him on Twitter. Other LIV Golf League players also performed well, with four finishing in the top 20. The league's success should put an end to the narrative that it's a league of aging and injured golfers who aren't able to compete at a high level anymore, said Bryson DeChambeau.
