AUSTIN, Texas (AP) — The final day lasted longer than Dustin Johnson wanted. The outcome was what everyone expected. Johnson, a golfing machine with no discernible weakness and hardly any pulse, won the Dell Technologies Match Play on Sunday for his third straight victory, this one making him the first person to sweep the four World Golf Championships. He had to work the hardest for this title. Johnson was taken to the 18th hole in the semifinal before making an 8-foot putt to beat Hideto Tanihara, and then Jon Rahm rallied from 5 down with 10 holes to play until his fearless charge fell short on the final hole. Johnson tapped in a 30-inch putt for a 1-up victory, completing a dominant week in which he never trailed in the 112 holes he played over seven matches. “What am I going to say that you guys don’t know?” Rahm said.
