Thomas matches record as he extends Sony Open lead

Updated: 

Justin Thomas further strengthened his grip on the Sony Open after moving seven strokes clear in the third round.

After posting the lowest 36-hole score (123), runaway leader Thomas carded a five-under-par 65 in Hawaii to tie the 54-hole record on the PGA Tour.

The dominant American - seeking his fourth PGA Tour title after taking out the Tournament of Champions earlier in January - produced a flawless display on Saturday by holing five birdies without dropping a shot to be 22 under heading into the final round.

After birdieing his final hole on the front nine, Thomas then picked up shots at the 10th, 14th, 16th and 18th holes to extend his advantage over the chasing pack at Waialae Country Club in Honolulu.

Thomas' nearest challenger is countryman Zach Johnson, who improved one position following his penultimate-round 65.

A stroke further back are Justin Rose (66), Gary Woodland (68) and Hudson Swafford (66).

At 13 under are Jamie Lovemark (65), Russell Knox (66) and Kevin Kisner (60).

Former world number one and two-time major champion Jordan Spieth is 10 shots off the pace.

Spieth shot a 66 after birdieing his final hole to ensure he rose up the leaderboard over the weekend and into sole possession of ninth place.
