Viktor Hovland shot an even-par 70 and is three strokes behind leader Sam Burns heading into the final round of the U.S. Open.

The National Weather Service reports that the weather in the Oakmont, Pennsylvania, area on Sunday is expected to feature rain showers in the morning and scattered showers throughout the day, with a high of around 76 degrees.

Sam Burns make a mockery of Oakmont's brutal challenge with a brilliant round to take the US Open lead. This is the eighth time Burns has held the 36-hole lead since he joined the PGA Tour (his first in a major) and his conversion rate is not good to say the least.

Johnny Miller, of Hilton Head Island S.C., who started his final Open round Sunday, June 17, 1973 six strokes behind the leaders and 3-over par 216, takes over fourth round lead with a charging 5-under par by birdie on the 15th, where he raises his hand after sinking the putt in Oakmont, Pa.
