UNIVERSITY PLACE, Washington (Reuters) - Dustin Johnson and Henrik Stenson moved into a tie for the early U.S. Open lead on Thursday while Phil Mickelson made an encouraging start in his bid for a career grand slam of the four majors.
Long-hitting Johnson took advantage of calm conditions on a firm and fast-running Chambers Bay layout as he fired a five-under-par 65 in the year's second major, which is being played for the first time in the Pacific Northwest.
