THOUSAND OAKS, Calif. -- Justin Thomas went from a fast finish one day to a fast start the next, and it carried him to a 7-under 65 on Friday and a 1-shot lead in the Zozo Championship at Sherwood.
Thomas wasn't particularly thrilled, except with his position, mainly because the final stretch of holes was still fresh on his mind and he closed with six consecutive pars on a day when the field made birdie or better just over 33% of the time.
Richy Werenski led the way with 12 birdies for a 61, the lowest score in a tour-sanctioned competition at Sherwood. The average score was 67.87.
Tiger Woods managed to beat that, making eight birdies in his round of 66, and he still didn't pick up any shots against the lead. The defending champion at the Zozo Championship -- he won last year in Japan -- was still 12 shots behind.
''Got off to a much better start and kept rolling,'' Woods said.
Thomas finished late Thursday afternoon with a 29 on the back nine at Sherwood for a 65. He began the second round on the back nine and ran off four straight birdies, chipping in on the par-3 12th, and played it in 31.
But after two birdies in three holes to start the front nine -- he hit into the water on the par-5 second hole and still managed to escape with par -- he didn't convert any birdie chances.
Griffin tied Thomas with a 5-foot birdie on the seventh hole and then a 5-iron that didn't turn out the way he had envisioned -- he aimed 25 feet left and hit it right at the flag, 15 feet behind it.
''Pushed it right at the flag and it lands a foot from the hole,'' Griffin said. ''Then Rickie [Fowler] hit right where I was trying to hit it and his caddie said, 'Good shot.' And I said, 'Yeah, that's where I was trying to hit it.'"
It worked out fine, but he dropped back with a clunky 9-iron on the ninth hole that came up nearly 30 yards short of the hole and a missed 10-footer for par.
Low scores were everywhere on a course that is short by PGA Tour standards and has five par-5s that are reachable in two, even without hitting driver off the tee. There has been pleasant weather with little wind. And different from the days of Woods' holiday event in December, a 78-man field makes it likely more players are going low, especially when they see what everyone else is doing.
Woods couldn't have played much worse than he did Thursday, especially on the par-5s. He played them in 3 over in the opening round of 76, his highest score in his 13th year playing Sherwood. He played them in 4 under on Friday.
Phil Mickelson played them in 3 over Friday, but it was really just a couple of par-5s that ate him up.
He sent his tee shot off the property to the left on the 11th hole and made bogey. And on the 13th, he sent two shots into what amounts to a jungle left of the fairway and made a quadruple-bogey 9. He shot 74 and was near the bottom of the pack, one week after winning for the second straight time on the 50-and-older PGA Tour Champions.
Making birdies is not a problem for Rory McIlroy. He's just not getting much out of them. McIlroy made seven birdies in the opening round, but he had three bogeys, two double bogeys and one club snapped over his knee on the back nine. On Friday, he made eight birdies and still managed only a 67.
''So I've made 15 birdies in the first two days, which usually would put you right up at the top of the leaderboard. I just made too many mistakes,'' McIlroy said. ''It was the same story last week, sort of the same story at Winged Foot. Just one of those stretches where the good stuff's there, but the bad stuff is sort of taking away from the fact that I'm hitting good shots and making birdies.''
Thomas has won the past four times he had a 36-hole lead, though this is different. Twenty players were within 4 shots of the lead, all of them at 10 under or better. He is playing well, making birdies, and it was no time to let up.
''I played well. I'm not very pleased with the finish,'' he said. ''The last six holes, I would have liked to at least have got something. Having a 5-iron and a 5-wood out of the fairway into two par-5s and making two pars is not good. I just wasn't near as tight and tidy those last four holes.''
