Scott Brown, a co-leader after the first round at the Farmers Insurance Open, shot a two-under par 70 in the third round on the South Course at Torrey Pines on Saturday and is tied for the lead with K.J. Choi, who shot an even-par 70.
Each is nine-under par, one ahead of Jimmy Walker and Gary Woodland heading into a final round in which tee times have been moved up in anticipation of a storm moving into the San Diego area.
Brown is looking for his second PGA Tour victory, his first having come in the Puerto Rico Open in 2013. Choi, 45, is seeking his first PGA Tour victory since the Players Championship in 2011.
"It's [the South Course] a tough golf course. But it's fair. It's just tough," Brown said. "If you're out of position, you just have to kind of play for par or bogey and you can't make any big numbers out here, because as soon as you get behind the eight ball, you can't press and try to make birdies. You've got to kind of plot yourself around here and hopefully you get a few good looks."
The Swede Jonas Blixt had the best round of the day, shooting a six-under 66 to move up 52 places on the leaderboard. Blixt is now tied for fifth, along with John Huh, Michael Kim and Freddie Jacobson. All trail the leaders by two.
Dustin Johnson, just one shot off the lead after Friday, shot a two-over 74 in the third round, bumping him back to ninth place. Looking for his first win in nearly a year, Johnson is now three shots off the lead at six-under.
