SAN DIEGO—Kevin Yu of Taiwan shot a bogey-free, 8–under 64 on the North Course at Torrey Pines to take a one-shot lead over Patrick Cantlay and Ryo Hisatsune in the opening round of the Farmers Insurance Open on Wednesday.
The eight lowest scores came on the North Course, which generally plays a few strokes easier than the South Course on the municipal layouts on a bluff high above the Pacific Ocean. Players have a round on each course before the cut. The final two rounds will be played on the South Course.
