OWINGS MILLS, Md. -- Robert MacIntyre ducked his head under the branches and climbed into a mess of bushes behind the fifth green without a golf club, first seeing if he could find his ball and then deciding if it was worth trying to play it.

If Robert MacIntyre wants to win his first PGA Tour event this season, he’ll have to beat the best golfer on Earth on Sunday at Caves Valley Golf Club. He’ll have to stare down Scottie Scheffler in front of a hostile crowd,
