PEBBLE BEACH — Russell Knox matched his career low on the PGA Tour on Thursday by firing a six-under par 64 to seize a share of the first-round lead at the Pebble Beach National Pro-Am.
Knox, who birdied four of his final eight holes on the Shore Course on Thursday, shares the lead at six-under with American Hunter Mahan, who played the Pebble Beach Golf Links course.
The 156-player field rotates between three courses in the first three rounds, comprising Spyglass Hill, Shore and Pebble Beach, while playing with amateurs. Pebble Beach will host the final round.
The 27-year-old Scotsman Knox played the back nine first on Thursday, making birdie at 11 and 12.
After a bogey on No 14, he rolled in another birdie on No 15 and then made it two in a row as he also birdied the par-four No 16. Knox moved to five under by making birdie at the sixth and his final birdie of the day came at the par-four eighth.
