In the span of about two hours on Sunday, J.J. Spaun looked like a golfer in complete freefall. It looked like the magic touch from his first three rounds at Oakmont Country Club had completely abandoned him.

The U.S. Open being completed on Sunday is now dependent on the weather and daylight cooperating at Oakmont. NBC's Mike Tirico reported that the U.S. Open could withstand a two-hour weather delay and still finish the final round on Sunday. The delay ended up lasting less than two hours indicating the final round could be completed as scheduled.

The U.S. Open has turned into a sprint through the soggy fairways of Oakmont following a downpour that caused a delay of 1 hour, 37 minutes

"I felt like I had a chance, a really good chance to win the U.S. Open at the start of the day. It just unravelled very fast," Spaun said, as quoted by ESPN . "But the break was actually the key for me to winning this tournament."
