Dustin Johnson has history on his side going into the weekend at the U.S. Open.
Johnson became the seventh player to lead by at least four shots after 36 holes in more than a century of this 72-hole championship. Only one player failed to win the trophy, and that was in 1909 when Tom McNamara sputtered on the weekend.
Johnson was the only player under par — 4-under 136 — and led by four shots over Scott Piercy and Charley Hoffman.
Three major champions were within five shots — Henrik Stenson, Justin Rose and defending champion Brooks Koepka. The sun was out, and there was just enough wind in the Hamptons for Shinnecock Hills to remain the tough test it has been over the opening two days.
