Defending US Open champion DeChambeau and record six-times runner-up Phil Mickelson were the high-profile players to miss the halfway cut

PGA golfer Victor Perez of France became just the second player to ever card an ace at the U.S. Open at Oakmont Country Club during the second round on Friday.

From an overhead view, the sight is somewhat jarring. The Pennsylvania Turnpike essentially cuts Oakmont's golf course in half.

Sam Burns held the second round clubhouse lead at the U.S. Open on Friday as overnight leader J.J. Spaun struggled late at Oakmont Country Club while Rory McIlroy was flirting with the cutline and Bryson DeChambeau looked certain to head home early.

Burns, statistically the world's best putter, hooped a clutch par save to shoot 65 Friday at Oakmont and enter this U.S. Open weekend at 3 under.

The U.S. Open is often one of the toughest tests in golf, and Oakmont Country Club is one of its tracks that is living up to its expectations.

One man who wasn’t cursing, however, was Sam Burns, who posted the third lowest score in Oakmont’s U.S. Open history with a remarkable second-round 65. That’s a full 10 shots better than what Rahm mustered on Friday, but let’s just keep that between us … at least until Rahmbo cools down.

Oakmont Country Club doesn’t yield much, especially holes-in-one. Prior to Friday, just one competitor in nine previous U.S. Opens at Oakmont had recorded an ace. That was Scott Simpson on the par-3 16th hole during the first round in 1983.

Attending the U.S. Open can be a ton of fun, but simply being able to watch golf on the game's grandest stage is an incredible treat each year. We here at CBS Sports are thrilled to bring you wall-to-wall coverage of the U.S. Open all weekend long.
