This caught my attention:
With so many technological advances in golf in the last 20 years, placing a pin near a bunker or by a tier on a green is one way to combat golfers’ hitting tee shots that travel 300 yards. But Mutch said the officials try to balance their pin locations. On Riviera’s back nine, he chose four on the left side of the green, four on the right, and one near the center. Not every pin can be in a treacherous, devilish position.A bit formulaic, no?
“For wedges, you’d put it three or four paces from the edge of the green,” said Mickey Bradley, a PGA Tour rules official. “For a 4-iron, you’d put it five, six or seven paces from the edge.”
