Scottie Scheffler delivered another example Saturday at Royal Portrush why he has dominated golf the last three years. He was the only player in the last eight groups not to make a bogey on his way to a 4-under 67 that allowed him to open a four-shot lead as he goes for the third leg of the career Grand Slam.

Scheffler played bogey-free on Saturday, has only one bogey in his past two rounds and three all week. He does not — and will not — back up.
