The majority of the players are finally on the course, but Phil Mickelson's 3-under 67 is still good enough to lead the 2013 U.S. Open.
While Mickelson still leads, a few players in later groups have gotten off to solid starts. Estanislao Goya, Carl Pettersson and 2013 Masters champion Adam Scott are one stroke back at 2-under. After opening with two pars, Scott recorded back-to-back birdies to move to 2-under through four.
There is a nine-way tie for fifth place at one under, a group that includes Luke Donald, Rory McIlroy, Lee Westwood and Ernie Els. Tiger Woods, playing in a group with McIlroy and Scott, is not off to as good of a start. Woods bogeyed No. 1 and No. 3 and is currently 1-over through four holes. Woods found the rough on his first two holes and has had scramble in the early going.
Here is a look at how a few notable names are performing on Thursday with a complete leaderboard available at USOpen.com.
