Justin Rose shot a 10-under-par 62 to lead the Farmers Insurance Open as Brooks Koepka made his return to the PGA Tour with a 73.
Englishman Rose, 45, carded 10 birdies to claim a one-shot lead over American Justin Lower at Torrey Pines, with both players playing on the North Course.
Rose, who missed the cut at last week’s American Express tournament, said: “I feel like I managed my game really, really well today. I felt like I read the greens phenomenally, putted – as you could see – really, really well.”
World number 173 Lower lost his full PGA Tour card last year and only made this week’s tournament because of a withdrawal.
The 36-year-old, who had two eagles in his round, said afterwards that his “mind’s not really here” because his wife is 34 weeks pregnant with twins.
“I’m just trying to get home on Monday to help out as much as I can,” he added.
