Justin Rose holds a six-point lead in the Farmers Insurance Open as he seeks his 13th PGA win

England’s Justin Rose is in a strong position to secure his 13th PGA Tour win after extending his lead to six strokes at the Farmers Insurance Open on Saturday.

The 45-year-old, who led by four shots after the second round, recorded seven birdies in a stunning four-under-par 68 on Torrey Pines’ stunning south course to finish at 21 under for the tournament.

American Joel Dahmen, who had five birdies and a bogey in a round of 68, holds a two-shot lead in the second.

Rose led from the first round and has the largest 54-hole lead in a tournament since Tiger Woods led by eight in 2008.

The best winning score in the history of the tournament is 22-under-22 – by Woods in 1999 and George Burns in 1987.

“My only hope is that he didn’t set an alarm or somehow start hitting hard on the back nine,” Dahmen told PGA Golf.

“The way he plays and what he does, I would be happy with second place.”

Rose, who was runner-up at the 2025 Masters, notched his last PGA Tour win in August, winning the FedEx St Jude Championship.

After shooting rounds of 62 and 65, Rose was in complete control until bogeys on 11, 12 and 16 trimmed what had been an eight-shot lead.

“It’s another great round in good weather on a great golf course,” Rose told PGA Golf.

“There will never be any complacency.

“I think there’s always enough respect for the game of golf in your mind that you’ve got to do everything right tomorrow. You’re going to go out, you’ve got to be focused, you’ve got to play well.”

Five-time major winner Brooks Koepka, in his first tournament back on the PGA Tour since leaving LIV Golf, shot a one-over-par 73 to head into the final round tied for 61st.

Irishman Seamus Power, who was four shots behind after his second round, is now back in 10th place after a disappointing third round 74.
