Masters champion Scottie Scheffler continued his dominance by winning the storm-delayed RBC Heritage in South Carolina for his fourth win in five starts.

The world number one, 27, carded a three-under-par 68 in the final round to finish on 19 under and win by four shots from fellow American Sahith Theegala.

Sunday’s final round was halted for more than two hours by inclement weather before darkness stopped play from finishing.

Scheffler returned Monday with a five-shot lead and three holes to play and he wrapped up a comfortable triumph.

He becomes the first player to follow a Masters win with victory at the RBC Heritage since Germany’s Bernhard Langer in 1985.
