American Russell Henley holds a three-stroke lead at the halfway mark of the Sony Open in Hawaii after a seven-under-63 on Friday.

Henley, who won the Sony Open in 2013, carded an eight-under-62 on the opening day and backed that up to be 15-under and three shots ahead of second-placed Haotong Li.

Li along with third-placed Matt Kuchar and equal fourth Chris Kirk all carded rounds of five-under-65.

Kirk is one of 10 players tied for fourth alongside Seamus Power, Stewart Cink, Corey Conners, Adam Svensson, Keita Nakajima, Davis Riley, Dylan Wu, Brandt Snedeker, Payton Kizzire and 2021 Masters winner Hideki Matsuyama.

Henley's seven-under-63 was a round-best alongside Cink and Charles Howell III who both surged up the leaderboard.

The 32-year-old American had an even card on the second round before holing a bunker shot for eagle on the 18th hole, his ninth hole of the day.

Henley came home strong with four birdies and an eagle in his final six holes, including a 29-foot eagle putt. He has three PGA Tour titles across his career, the last being in 2017.

Veteran Jim Furyk dropped well off the pace after his fast start, with a two-over-round of 72 leaving him six under at halfway, while day one leader Kevin Na slipped to eight under after a round of one-over-71.

Jim Furyk rolled back the years with a hole-in-one at the Sony Open to finish the opening round in Hawaii one shot behind leader and defending champion Kevin Na.

The 51-year-old, who has 17 PGA Tour victories to his name, sunk the perfect shot on the par-three 17th on his way to finishing eight under on Thursday.

Furyk was hampered by a slow start at Wai'alae Country Club with a bogey on the opening hole, though that proved to be the American's only dropped shot in a round of 62.

That makes Furyk the oldest player to shoot 62 or better on the PGA Tour since 1983 as he looks to win the tournament for a second time, 26 years on from his previous triumph.

"I'm trying to get ready for this year. I want to be competitive this week," said Furyk, who made the sixth hole-in-one of his career and first since 2011.

"I want to compete and put myself in position, in the hunt, and also want to get a feel for where my game is and what I want to work on for the year."

Furyk will resume day two level with compatriot Russell Henley and a stroke behind blemish-free Na, who is aiming to defend the crown he won last year.

Na was on course for a sub-60 round, but three good birdie chances passed him by and he now has seven challengers within two shots of his lead.

The South Korean settled for 61 to tie his career-low round on the PGA Tour. He leads the way for the most rounds-of-62 or better since such data was first recorded in 1983 (10).

Na, Furyk and Henley are three of six past Sony Open winners in the top 10 after day one, along with Matt Kuchar, Patton Kizzire (both six under) and Ryan Palmer (seven under).

Elsewhere, Cameron Smith could not build on his record-breaking win at last week's Sentry Tournament of Champions as a couple of bogeys left him three-under par in a tie for 40th.
