U.S. Open leader Dustin Johnson is heading down the back nine at Oakmont unsure of what to jot down as his score on the fifth hole.
The USGA has told Johnson it will review what happened on the fifth green after the Irmo native completes the final round of the tournament later Sunday evening.
Johnson was standing over a 6-foot putt for par on the 390-yard par 4 when the ball appeared to move ever so slightly. Johnson was taking a few practice strokes behind the ball when it moved just a touch. It moved again just as Johnson moved the putter behind the ball to hit. Johnson stepped away from the ball and asked for a ruling. He then made the putt and moved on to the next hole.
There was no immediate penalty given to Johnson, though USGA officials told him they wanted him to take a look at the tape after the round.
Johnson is temporarily a 5-under through 13 holes of the final round. That’s one better than third-round leader Shane Lowry and two ahead of resilient Scott Piercy.
