Joaquin Niemann learned a lesson the hard way during the 2026 U.S. Open when he was surprised with a two-stroke penalty ahead of Friday’s second round for his actions the night before.
Niemann, who will start his 2026 British Open with a 7:25 a.m. ET tee time alongside Sepp Straka and Kurt Kitayama on Thursday, will have to watch his conduct at Royal Birkdale, as well.
