Sam Burns and Adam Scott started the last round of the U.S. Open in the final group, one shot separating them in first and second place.

Like any savvy patient who gets a bad diagnosis, Sam Burns wanted a second opinion. When his drive on Oakmont’s par-4 15th hole stayed on the fairway next to the first cut, he seemed to catch a good break. But when Burns arrived at the ball, it looked and felt to him that it was sitting in standing water from the day’s earlier heavy rain storm.

Sam Burns took a one-shot lead into the final round of the U.S. Open at Oakmont. From there, things did not go well.

Burns converts the birdie following a brilliant tee shot on the par-3 13th. He’s at 4 under, one clear of playing competitor J.J. Spaun. The 44-year-old birdies the par-3 13th to get to 1 under. He’s two off the lead, seeking his second major title (2013 Masters).

It just showed a clever bit of awareness and foresight. In the heat of the pressure and the pouring rain, Burns stopped himself from making a potentially very costly error. It was a small moment, but the kind of decision that wins U.S. Opens.

Sam Burns has had a stellar week at the U.S. Open, but the PGA Tour golfer is used to playing with high-profile partners. With Burns in contention to win the U.S. Open, fans pointed to an old Instagram post Burns made last fall.
