Five-time runner-up Phil Mickelson grabbed the early clubhouse leader in the first round of the US Open.
He didn't get much sleep before his first round began, but as it turned out it didn't really matter.
After attending his daughter's eighth-grade graduation on Wednesday in San Diego, Mickelson flew cross-country through the night and arrived at the Merion Golf Club in Ardmore, Pa., just four hours before his 7:11 a.m. tee time.
He then proceeded to shoot an opening round 3-under-67
It was his lowest opening round since 1999 in the Open.
Former Masters champ Bubba Watson, Dustin Johnson and Steve Stricker were among those who shot a 1-over-71. Sergio Garcia had to settle for a 3-over-73.
On the course Tiger Woods is 2-over through 10 while Rory McIlroy is even after 11 holes of play.
Webb Simpson is the defending champ.
