In a field that featured the top five players in the world, Johnson made a strong opening statement that the No. 1 ranking he has held for nearly a year might be difficult to take away.
Johnson stretched a two-shot lead to six strokes at the turn, then delivered the biggest moment of the week with a drive on the par-4 12th hole that stopped 6 inches from the cup for a tap-in eagle.
He finished at 24-under 268 for his 17th career victory.
“Plenty of horsepower here.”
