Jordan Spieth turned out to be the star attraction Friday playing with Tiger Woods at Torrey Pines in San Diego.
Spieth again showed game well beyond his 20 years with a 9-under 63 on the North Course, giving him a one-shot lead over Stewart Cink going into the weekend at the Farmers Insurance Open. Cink drilled a 3-wood from 280 yards onto the green at the par-5 ninth on the tougher South Course for a two-putt birdie and a 1-under 71.
Woods rarely gets upstaged at Torrey Pines, where his eight professional wins include the 2008 U.S. Open. But in his first competition in six weeks, he shot a 1-under 71 on the North. Woods' only birdies came on his opening hole and on his sixth hole, a flip wedge to 4 feet, and he was nine shots behind.
It was the first time Spieth has played with Woods in a tournament, and the Texan played as if it was any other round on the PGA Tour.
"Any time you can shoot a lower score than a 66 or 65 and you can really get it deep and be in a zone and not worry about what your score is ... that's special," Spieth said. "That's proving that I can play my best golf when it matters on a PGA Tour venue. Each time you can do that, you get more and more confident that you can do it more often."
Spieth was at 10-under 134 and will be in the last group Saturday with Cink and Nicolas Colsaerts, who shot 67 on the South and was two shots behind.
"The kid's got talent," Woods said of Spieth. "He hits it a long way, phenomenal putter. He made a boat load of putts today from the 10- to 20-foot range. He putted with a lot of confidence."
That wasn't the case for Woods.
"I wouldn't say it's rusty," he said. "I was just a fraction off, and at this level and on courses like this, if you're just a fraction off it doesn't take much."
Meanwhile, Phil Mickelson withdrew Friday night because of muscle pain in his back. He had a 1-over 73 on the South in the second round, leaving him eight shots back.
Mickelson said after the round that he feared getting into bad habits by altering his swing to keep his back from hurting. This is his hometown tournament.
Mickelson is scheduled to defend his title at the Phoenix Open next week, then play at the AT&T Pebble Beach National Pro-Am the following week.
Former Cal star Michael Kim missed the cut in his pro debut, struggling to an 80 on the South for a 150 total.
LPGA Tour: Jessica Korda took the second-round lead in the season-opening Bahamas Classic, birdieing four of her last seven holes in high wind for a 7-under 66. The 20-year-old was at 11-under 135 at Paradise Island's Atlantis Resort.
Pleasanton native Paula Creamer, playing alongside Korda, was a shot back after a 65. She drove left on the first hole and three-putted from 7 feet. She birdied 10 of the last 17 holes. "After that, I said, 'Let's go make some birdies.' And I did," said Creamer, winless since the 2010 U.S. Women's Open.
Stanford grad Michelle Wie (65) and Jenny Suh (66) were at 137.
