Scheffler led Taylor Pendrith by a stroke, with PGA TOUR rookie Jackson Suber three strokes off the pace.

World No. 2 Rory McIlroy, making his first start after winning THE PLAYERS Championship earlier this month, stood 1-under total through seven holes Friday, one stroke off the projected cut line.

A band of thunderstorms was approaching from the southwest when PGA TOUR officials blew the horn to evacuate the course.
