Dustin Johnson is back to No. 1 in the world after a dominating performance at The Northern Trust in Boston.
Johnson played the final two holes in near darkness after a late storm delay and finished with a birdie for an 8-under 63 and an 11-shot victory over Harris English.
He finished an incredible 30-under for the 22nd victory of his PGA Tour career.
Johnson became only the third player to finish at 30-under par or better on the PGA Tour.
He was one shot from the record Ernie Els set in 2003 at Kapalua.
