LA QUINTA, Calif. —
Castro had nine birdies at PGA West’s Jack Nicklaus Private Course, and Hahn had nine birdies on PGA West’s Arnold Palmer Private Course.
“It was a great day,” Hahn said. “Chipped two in. Hadn’t done that since I was nine.”
Russell Henley, the Sony Open winner Sunday in Hawaii in his first start as a PGA Tour member, had a 64 on the Nicklaus course. He’s 32 under in his first five rounds this year.
“It was a perfect day,” Henley said. “The weather is perfect. The greens were true. So, it’s just trying to stay patient and let the birdies come to me.”
Mickelson made his first start since tying for second in early November in the HSBC Champions in China, the only event he played after the Ryder Cup.
“My timing and rhythm was off a little bit,” Mickelson said. “My putter was atrocious and I’ve been putting great, too. So, that was disappointing.”
