Matt Kuchar shot a bogey-free six-in-a-row 66 to extend his lead in the Sony Open on Saturday at Waialae Country Club in Honolulu .
He I go to the last round of Sunday at 18-under 192 with a lead of two shots on Andrew Putnam, whose strong start allowed him to tie for the lead early in the third round.
The 40-year-old Kuchar was three-under in the front and regained the first place. He ended the round with six consecutive pars.
Kuchar will aim for his second championship in about two months after winning the Mayakoba Golf Classic in November in Mexico.
Kuchar opened with consecutive rounds of 63 this week. He excelled again Saturday with the irons, leaving birdieputts of reasonable length behind.
Putnam even went with Kuchar with three birdies in the first five holes. At number 6 he had a chance for another birdie, but his chip from the pony was just outside the cup. That would have made the birds on three consecutive holes.
Keith Mitchell and Chez Reavie share 14th place in third place. Mitchell played a bogey-free round of 63, including four straight birdies on Nos. 7-10.
Reavie (66), who had three eagles Friday, was five-under by nine holes from Saturday's round. Then he went through a trajectory from three to eleven between 11 and 13 before he regrouped the rest of the way for two birdies.
Bryson DeChambeau made a move with 63 and scored his best score on the PGA Tour. He opened the round with birds on each of the first three holes.
He is one of the golfers under 11-under.
Corey Conners, Davis Love III, Charles Howell III, Dominic Bozzelli and Brian Stuard all start on the last round that ends at 11-under. They all checked in with 64.
Hudson Swafford (67), Ted Potter Jr. (68) and Marc Leishman (68) are also in the set at 11-bottom.
