Sam Burns is one round away from a U.S. Open title but has no margin for error against a star-studded tournament field.

With three rounds of the U.S. Open at Oakmont Country Club complete, Sam Burns holds a one shot lead and will look to close it out on Sunday and win his first major championship. Burns entered the weekend with the lead after finding ways to tame some of Oakmont's challenges, firing a 65 to move to -3 on the leaderboard.

The pounding rain arrived far too late to douse so many of the meltdowns across Oakmont on Friday in a U.S. Open that produced a brilliant round by Sam Burns and a litany of collapses and tantrums typical in a major that prides itself on being the toughest test.
