Following a 96-minute weather suspension, Spaun returned and proved to be the steadiest in the field.

J.J. Spaun overcomes five early bogeys to win the U.S. Open at rain-soaked Oakmont.

Needing two putts from 65 feet on the 18th to win, he finished this storybook week by holing the longest putt all week for birdie and a 2-over 72.

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.

Play was suspended with just five groups left on the golf course, as 13 players had to return to Oakmont on Saturday morning to finish up their second round before the third round got underway.
