Russell Knox was certainly ready to Hoola dance after producing his lowest score in 12 months and again at the Sony Hawaii Open.

Scotland’s top-ranked golfer was soaring with a 30-foot chip-in eagle ‘3’ and four birdies in a second equal best 64 round on day two of the PGA Tour at Honolulu.

The effort saw the Jacksonville-based Knox jump 53 places and into a share of 12th place in the $US 6.2m event being led by the in-form Brian Harman.

Not quite the same as soraing in Hawaii but Russell Knox on one leg at the Grand Canyon.

The left-handed Harman, who had been well in contention through 36-holes a week ago in Kapalua before eventually sharing third, eagled his 18th hole or the ninth of the course in a best-of-the-day 63 to lead by three shots at 10-under.

Except for the tropical warmth, the two golf courses on the Hawaii swing are nothing alike. The Plantation Course at Kapalua was built on the side of the mountain on the west tip of Maui and features fairways that can stretch nearly 90 yards wide and big slopes in the greens.

Waialae is at sea level — waist-high hedges along the 16th and 17th holes and behind the 11th green are all that separate grass from the beach — with smaller, flatter greens and fairways framed by trees.

“The biggest elevation change here is from the walk down from the hotel,” Harman said. “I’ve always kind of felt like as long as there’s fairways and greens and holes to putt it, then I’m going to be fine.”

Knox’s effort is his lowest round since a similar 64 on day one of the 2017 Hawaiian Open and also his lowest in 17 rounds of the new 2017/18 wraparound schedule.

It was a clear tale of two nines for the current World No. 80 ranked Knox who was just one under over his outward nine before storming home under a wet sail with birdies at the first, third and seventh holes of the course and like Harman Knox eagled the last.
