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 final round was halted at 4:05 p.m. after torrential rain soaked Oakmont, leaving standing water on the greens and in fairways.

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
