Two Americas currently sit atop the early leaderboard at the 2012 U.S. Open -- and no, it's not Tiger Woods or Phil Mickelson. Kevin Na currently is tied atop the leaderboard with a score of -3 through his first nine holes. Na started on the back nine, so he'll head over to the front nine to finish his first round off.
Branden Grace also sits at -3 through his first nine holes, tied with Na.
Tiger Woods, Phil Mickelson and Bubba Watson, who constituted a superstar pairing on Thursday, are all currently struggling. All three are through eight holes, and Woods currently sits at +1, while Watson and Mickelson are struggling at +4.
Along with Na and Grace, seven other golfers are under par in the early goings of the first round. Jason Bohn sits one stroke behind Na and Grace, at -2 through his first eight holes. A full leaderboard can be viewed here, at the U.S. Open's official website.
