AUSTIN (REUTERS) - Dustin Johnson became the first player to win all four World Golf Championships events when he claimed the WGC-Dell Matchplay in Texas on Sunday.

World No. 1 and top seed Johnson beat Spanish 21st seed Jon Rahm 1-up in the 18-hole final at Austin Country Club.

Johnson built a 5-up lead after eight holes and held on despite a late Rahm rally that cut the lead to 1-up after 16 holes.

Earlier on Sunday, Johnson barely survived his semi-final against 54th seed Hideto Tanihara, winning 1-up after the Japanese player missed a good chance to win the 18th hole. Rahm beat American 42nd seed Bill Haas 3&2 in the other semi-final.

It was Johnson's third consecutive victory, after he won the event formerly known as the Los Angeles Open and then the WGC-Mexico Championship.

Johnson's five WGC titles puts him second behind Tiger Woods, who has 18.
