I’ve watched that and many other Bryson DeChambeau youtube videos. I think that’s the closest he’s come to breaking 50. Maybe one other person equalled it with him.
Sergio maybe?
I watched it too. In fairness, with a player the caliber of Bryson playing from the up tees, breaking 50 should be within his grasp. I watched him play on another YouTube page where he played with a child’s set of clubs. It is unfair to be so good.
