Prime Sports Golf: U.S. Open Sunday Special

Greg DePalma, PSN managing editor Jeff Shain and Joel Cook from Pro Golf Weekly preview the final round of the U.S. Open, where more records were set at Erin Hills on Saturday as Justin Thomas matched the Open scoring mark with a 63. Brian Harman has been steadiest, though, and takes a one-shot lead into Sunday over Thomas, Tommy Fleetwood and Brooks Koepka.
