Wyndham Clark takes a huge six-stroke lead into the final round of the 2026 US Open, with the 2023 champion carding a level-par 70 on Saturday. Clark's closest challengers, at one-under-par, are World No.1 Scottie Scheffler, Sahith Theegala, Tom Kim and Sam Stevens, and he'll have Scheffler for company in the final group on Sunday. Scheffler turns 30 on Sunday and could celebrate his birthday in style by completing the career grand slam, but he has plenty of ground to make up.
