Bryson DeChambeau had eyes down and lips moving as he made his way to sign his scorecard Friday in the PGA Championship, muttering to himself every step of the way. DeChambeau looked like someone who had thrown away a good round.

It was the first meeting between the two major winners after Bryson DeChambeau said Rory McIlroy wouldn't talk to him at the Masters.

While DeChambeau admitted The Open Championship remains a mystery that continues to befuddle him, what the big hitter has largely solved are the three United States-based major championships: the Masters, PGA Championship and the U.S. Open.
