Dustin Johnson delivers 1-2 blow as he wins PGA playoff at The Northern Trust

OLD WESTBURY, N.Y. (AP) — In a FedEx Cup playoff opener that felt like a heavyweight bout, Dustin Johnson delivered back-to-back blows to beat Jordan Spieth in The Northern Trust.

One was a putt from 18 feet.

The other was a drive that traveled 341 yards.

Down to his last shot, Johnson watched his 18-foot par putt stay on the high side of the hole and thought for sure it would miss. He took two steps of hope to the right, and then pumped his fist in a rare show of emotion when it swirled around and dropped in the back side of the cup for a 4-under 66 to force a playoff.

Given new life, Johnson relied on his strength and powered a drive over the lake to the far edge of the fairway. It was the longest drive all week on the 18th hole, and it left him a 60-degree wedge to 4 feet for birdie and a victory he badly needed.

The No. 1 player in the golf finally looked the part again.

Spieth lost for the first time in six tries when leading by two shots or more, and there wasn’t much he could do except take back that tee shot into the water on the par-3 sixth hole after building a five-shot lead. Johnson played bogey-free over the final 29 holes.
