Dustin Johnson holed an eagle putt at the first play-off hole to win the LIV Golf International in Boston and land the first prize of $4m.

The two-time major winner beat Chile’s Joaquin Niemann and India’s Anirban Lahiri in a three-way play-off after they all finished the 54-hole tournament on 15 under par.

Lee Westwood fired an 8-under 62 in the final round, the lowest round in LIV Golf history, but he bogeyed his last hole to miss the play-off by one and finish joint fourth alongside Open champion Cameron Smith, who was making his LIV debut.

Johnson carded a closing 65 with his sixth birdie of the day coming at the 13th, but he failed to make another birdie and needed par saves at the final two holes to make the play-off.

Johnson, who finished eighth in the inaugural LIV Golf event in London, fourth in Portland and third at Bedminster, became the first American to lift the individual trophy in the series. In the play-off, sent his eagle putt at the par-5th 18th racing up the hill and although the ball hesitated when it hit the lip, it then hit the back edge of the cup and bounced in.

“Yeah, it was going a little fast, but it was a good line,” said Johnson, adding that he felt the 18th “owed me one” after his second shot in regulation ended up in the underbrush alongside the giant scoreboard behind the green.

As well as the first prize, Johnson also picked up $750,000 as his share of the team first prize for his 4 Aces outfit, which finished two strokes better than Lahiri’s Crushers. The other members of 4 Aces were Taylor Gooch (6th), Pat Perez (15th) and Patrick Reed (31st).
