The narrative for the 2013 U.S. Open is beginning to take shape, and if the developments that have occurred thus far hold true, the weekend promises to bring plenty of drama at golf's second major.
Thankfully, plenty of media sources are on top of their games to bring you the latest information in the 113th edition of this prestigious tournament in Ardmore, Pennsylvania.
Phil Mickelson led at the end of the first round and a closing birdie allowed him to tie Billy Horschel for the lead. Horschel's round of 67 featured him finding all 18 greens in regulation in a stunning display of ball-striking.
After 36 holes of one-under-par golf, Mickelson and Horschel are the only ones in the field in red figures.
Luke Donald surged to the front early on, spurred by a chip-in at the par-three 13th hole to get to minus-four.
