Harris English secured his first win since 2013 with a play-off victory at the Tournament of Champions on Sunday.

The American carded a four-under 69 in the final round to finish alongside Joaquin Niemann (64) at the end of regulation in Kapalua, Hawaii.

English stepped up to birdie the par-five 18th hole in the play-off, overcoming Niemann for his first win since 2013.

"It's incredible," he told the Golf Channel after his third PGA Tour success.

"A lot of hard work over the years, you never think you're going to get here again, winning twice back in 2013 and it's just hard to win out here.

"I had a really good chance this week and felt good about my game and you've just got to get it done."

Niemann produced a stunning nine-under 64 in the final round to finish at 25 under.

But English birdied his final hole to force a play-off and he delivered to secure the title.

Two-time champion Justin Thomas (66) finished at 24 under, a shot ahead of Ryan Palmer (71).

Im Sung-jae (69) and Xander Schauffele (66) ended up tied for fifth at 21 under.

World number two Jon Rahm got going with a six-under 67, but it was only enough to finish tied for seventh alongside Bryson DeChambeau (66) and Collin Morikawa (73).

Dustin Johnson, meanwhile, carded a second straight 69 to finish tied for 11th.

Harris English pulled two strokes clear at the halfway mark of the Tournament of Champions as Dustin Johnson and Jon Rahm made their moves.

English, who shared the overnight lead with Justin Thomas, carded a six-under 67 in the second round in Kapalua, Hawaii on Friday.

The American produced a bogey-free round that featured six birdies to move into 14 under at the first PGA Tour event of 2021.

English is two shots ahead of Thomas (69), Daniel Berger (65), Collin Morikawa (65) and Ryan Palmer (67).

Thomas, a two-time champion of the tournament, made four birdies on his front nine but a bogey at 13 slowed his momentum before picking up another shot at the last.

The world's two top-ranked players, Johnson and Rahm, charged into contention.

Johnson, who opened with a 71, made eight birdies in a second-round eight-under 65 to get to 10 under – enough for a tie for 10th.

Rahm is alongside him after the Spaniard produced a fast finish, birdieing five of his final seven holes.

Xander Schauffele (66), Brendon Todd (67), Im Sung-jae (68) and Patrick Reed (68) are tied for sixth at 11 under.

Joining Johnson and Rahm at 10 under are Scottie Scheffler (66), Bryson DeChambeau (67), Joaquin Niemann (67), Carlos Ortiz (67) and Patrick Cantlay (68).

Justin Thomas carded an eight-under 65 to share the lead after the opening round of the Tournament of Champions on Thursday.

Two-time champion Thomas produced a bogey-free first round that included eight birdies in Kapalua, Hawaii.

The world number three, winner of the event in 2017 and 2020, made five birdies on the front nine and three on his final five holes.

Thomas shares a two-stroke lead with Harris English in the first PGA Tour event of the year.

The highlight of English's round was an eagle at the ninth hole, where he chipped in from just off the green.

On what is a congested leaderboard, six players are tied for third at six under.

Sergio Garcia, Robert Streb, Nick Taylor, Ryan Palmer, Im Sung-jae and Patrick Reed all opened with 67s.

Garcia won the tournament in 2002, while Reed was victorious in 2015 and has two runner-up finishes since – including last year.

Adam Scott, Patrick Cantlay and Brendon Todd carded five-under 68s.

World number one Dustin Johnson is back in a tie for 30th after opening with a 71, while Jon Rahm carded a 70.
