Let's sum up where Dustin Johnson, who led the U.S. Open after Round 3 by three strokes, stands early in his Round 4 play.
Bad: Dustin Johnson triple-bogeyed the second hole.
Bad: On the third hole, Johnson hit his ball in a hazard. He found it, but only 15 seconds after the five-minute time limit expired. A second consecutive triple-bogey is a real possibility.
Bad: The players behind him -- Graeme McDonald, Ernie Els and Phil Mickelson in particular -- are going strong.
Bad: The NBC booth just called Dustin Johnson "Dustin Hoffman."
