Rory McIlroy lashed out at the toughest golf course in the country Friday as Oakmont Country Club continued to bare its teeth at the 156 men competing in the 2025 U.S. Open. Though McIlroy was hardly the only golfer to be frustrated by the difficulties he faced in Western Pennsylvania, he was perhaps the most demonstrative of the bunch.

The world's best golfers have had a terrible time of it over the first two rounds of the 2025 U.S. Open at Oakmont, with even Rory McIlroy and Scottie Scheffler visibly frustrated at times.

Burns had the low round for the week, a score that was posted three times when Oakmont last hosted the U.S. Open in 2016. There are chances out there — Victor Perez of France made a hole-in-one on the sixth hole in a roller-coaster round of 70 — but punishment is everywhere.

Sam Burns is a birdie machine at Oakmont, a label not many expected at this U.S. Open. By avoiding another sloppy finish, Burns posted a 5-under 65 on Friday and set the target for the late starters — and let Scottie Scheffler know the mountain he faced.

Simpson got some company in the Oakmont record books late Friday morning, however, as Victor Perez found the bottom of the cup from the tee on the 192-yard 6th hole, hitting a 7 iron just below the hole and watching as it released straight into the hole for an ace.
