Birdies were all-but rationed on Day 1 of the U.S. Open at Shinnecock Hills. But the course allowed a few more on a less windy Friday.
Overnight co-leader Dustin Johnson got the ball rolling - literally - with a birdie on the par-3 11th, his second hole of the day.
That got him to 2 under for the tournament. He was tied, momentarily, with Russell Henley. But while Henley started to back up, Johnson pressed forward.
The world No. 1 birdied the par-5 16th and made the turn in 2-under 33. At 3 under par for the championship, he held the outright lead.
Johnson bogeyed the par-4 first, but rebounded with this birdie at the par-4 fourth.
He then made this 45-footer for birdie at the par-3 seventh to reach 4 under par and take a three-stroke lead.
Johnson finished par-par for a 3-under 67.
