SAN DIEGO (AP) — Scott Piercy had the best score Thursday at Torrey Pines because he made nine birdies. Robert Allenby might have had the best round because he made no bogeys.
Adding to the complexity at the Farmers Insurance Open was Phil Mickelson. He was so excited to get his season started that he played with caution, yet one of his best birdies came after he hit his tee shot into the parking lot.
A glorious day along the Pacific coast ended under a clear sky, even if nothing about the leaderboard will clear up until the weekend. The tournament is played on two courses that couldn't be more different — the North Course is 712 yards shorter than the South Course, which hosted a U.S. Open two years ago.
Piercy played the North and watched his scores go south in a round of 8-under 64. He made seven birdies on the front nine and even entertained thoughts of a 59 until a bogey on his 11th hole. He was not the least bit devastated.
"I shoot 59 every day," Piercy said. "I just have to keep on going, usually."
He had a one-shot lead over Ben Crane, Chris Tidland, Ryuji Imada and Matt Every, with Tom Pernice Jr. another shot back after a 66. They all played the North Course, and will have to tackle the big South on Friday.
That's what made Allenby's round so impressive.
One of the hottest players in golf, Allenby made a couple of big par saves late in his day to protect a bogey-free round of 67, making him the only player among the top 15 after the opening round to play on the South.
He felt as though he were leading the tournament, even if he was tied for seventh.
"I gauge myself off this golf course," Allenby said. "This is a real golf course. If it wasn't, they wouldn't have had a U.S. Open here. I don't want to say the other course is Mickey Mouse because that would be rude. But it's Mickey Mouse-ish."
Ryan Palmer, who beat Allenby on the final hole in Honolulu two weeks ago, played in the group behind him and would have joined him with the low score on the South if not for a bogey on the 17th. Even so, Palmer was thrilled with his start, and couldn't help but notice the "NC" — North Course — listed next to all the names on the electronic leaderboard.
"There's definitely a lot of North Course scores," he said. "I'm fortunate to play well on this golf course. I'm happy to get out of there with a round under par."
Palmer was particularly thrilled with a par on the eighth hole, a par 3 with a shallow green. He was between clubs, so he measured two club-lengths on the tee box with his driver to move back and hit a 6-iron. Didn't matter. He still flew the green and was on the back slope of a bunker, trying to get close to a back pin. He bunted the shot into the rough and watched it barely climb onto the green, then made the par putt from 20 feet and felt as good as any of his birdies.
He played in front of the largest gallery, mainly because of the company he kept — Mickelson, the No. 2 player in the world who is getting plenty of attention this year as someone who could give golf a boost during the indefinite break of Tiger Woods.
They had the biggest crowd, even if it never topped more than about 750 people. The cheers for the occasional birdie were not enough to offset the military jets zooming out to the sea from nearby Miramar.
Mickelson played a steady hand in his round of 70.
"I was a little more cautious today because I didn't want to make too many big mistakes," Mickelson said. "I want to work my way into the tournament. (Jack) Nicklaus used to talk about that in majors, that he wanted to try to progress as the week went along, and I didn't want to try to come out and win the tournament on Thursday, because it's just not possible.
"I'm hoping I play better tomorrow and shoot a low score on the North, good enough to get myself in contention for the weekend."
Mickelson had a pair of bogeys from the fairway bunkers, and a three-putt bogey on the 10th. What helped was his exceptional play on the par 5s. He reached three of them with his second shot to set up two-putt birdies.
The other came on the 614-yard ninth.
Mickelson watched his drive sail way to the left, over a green-mesh fence along the fairway. He hit a provisional tee shot, then had a rules official meet him at the fence. Sure enough, his ball landed in a makeshift parking lot outside the Scripps medical clinic. Because the parking lot is considered a temporary immovable obstruction, he was given a free drop, and ultimately made a 12-foot birdie putt.
He sure wasn't thinking birdie as his tee shot cleared the fence.
"Probably unlikely, I would say," Mickelson said, grinning. "I've been over there before, and I had a pretty good idea that the parking lot was a temporary immovable obstruction. So I was able to get relief."
More relief should come Friday on the North Course, which played more than 2½ shots easier.

John Daly, whose last victory came at Torrey Pines in 2004, failed to make a birdie on the South Course and shot a 79. ... Tim Herron, who lost his card this year and is trying to Monday qualify or get exemptions, got into his first tournament when John Senden withdrew. He shot 71 on the South.
