US Open Leaderboard 2015: Updated Scores and Standings from Saturday at Chambers

It's moving day at the 2015 U.S. Open, which means golfers have 36 holes or less to make their climb up the leaderboard as Saturday's third-round action unfolds at Chambers Bay Golf Course.

Jordan Spieth entered Day 3 as the co-leader along with Patrick Reed at five strokes below par, but their lead is very much in danger with more than a dozen golfers also below par. The leaders don't tee off until 5:50 p.m. ET, so get ready for a long evening of action from University Place, Washington.

The scores don't exactly show it, at least not at the top. But Chambers Bay is giving some of the world's best golfers as many challenges as any U.S. Open in recent memory—and that's saying something.

The unconventional switch to a links-style course that is often used in Europe but hardly used in the U.S. isn't the only thing golfers have had to get used to. Sharp elevation changes, nasty, long fescue grass and inconsistent green surfaces have thrown golfers for a loop.

The hole placements can make it even tougher. See how Saturday's hole locations are set up, as per Play Chambers Bay:

Of course, some golfers aren't having that much issue with the course at all—most impressive of which has been the Ryder Cup pair from 2014, as Spieth and Reed continue their great form. Although they have succeeded as teammates, they're also used to beating each other, as Fox Sports' Shane Bacon analyzed:

While Spieth is looking to add major No. 2, he's the only one among the 16 golfers under par entering Saturday who has a major to his name. But there are a few names within striking distance who have grown accustomed to contention at the major level. One such player is Dustin Johnson, as Justin Ray of Golf Channel noted:

The U.S. Open has typically been a setting where new champions are crowned. Each of the last six U.S. Open winners since Tiger Woods' last major title in 2008 have been first-time major winners, including Rory McIlroy's breakthrough in 2011.

Unless Spieth is able to become the sixth golfer to ever go back-to-back at the Masters and U.S. Open or a former major winner comes out of the wreckage at par or worse, it looks likely that a seventh straight first-time major winner will take the U.S. Open with so many contenders in the mix.
