AUSTIN, Texas — Dustin Johnson won the Dell Technologies Match Play with more drama than he needed to cap off an otherwise dominant week that made him the first player to sweep the four World Golf Championships.

The scorecard will show Johnson never trailed in any of his seven matches over 112 holes, ending with a 1-up victory over Jon Rahm for his third straight victory that left no doubt who was No. 1 in the world.

The look of concern, especially as Rahm made a bold charge in the final hour Sunday, spoke to a long day.

Johnson was 4 up with six holes to play when the Spanish rookie with a big game and no fear hit driver over the water and onto the 13th green to win the hole with a birdie. He stuck a wedge close on the 15th for another birdie. Rahm hit a shot through the trees on the 16th and won the hole with a 30-foot birdie.

The rematch Rahm wanted against Johnson, who held him off in Mexico City three weeks ago, ended the same way.

His big rally was a little short.

Playing the 356-yard 18th hole for the first time in competition all week, and needing a birdie to send this heavyweight bout to overtime, Rahm smashed driver over the back of the green.

But his chip down the slope checked up and stayed short of the ridge, and he had to settle for par.

Johnson came up just short of the green, chipped to 30 inches and rolled in it to complete another big week.

PGA TOUR: D.A. Points started with five straight birdies and closed with a 6-under 66 to win the Puerto Rico Open in Rio Grande, Puerto Rico, for his third PGA Tour title.

The great start wasn’t enough for Points when he made three bogeys in a five-hole stretch around the turn. He steadied himself, protecting a one-shot lead going to the par-5 18th, and made birdie for a two-shot victory.

Retief Goosen, Bill Lunde and Bryson DeChambeau tied for second.

LPGA TOUR: Mirim Lee of South Korea shot a 7-under 65 to win the Kia Classic in Carlsbad, California by six strokes and tie the tournament record of 20-under.

It was her third LPGA Tour victory and first since winning two titles in 2014, her rookie year.

Lee, 26, tied the tournament record set in 2015 by Cristie Kerr, who tracked down Lee with a 65 to win by two strokes.
