Four share lead in La Quinta
Americans Jason Dufner, Jeff Overton and Jerry Kelly along with Indian Anirban Lahiri are joint leaders after the opening day of the CareerBuilder Challenge in La Quinta.
The four are level at eight-under par 64 after the first round.
Lahiri was the surprise packet of the day as he launched his first season as a US PGA Tour member with confidence.
The 28-year-old carded eight birdies in a flawless round, finding 11 of 14 fairways and all 18 greens in regulation at La Quinta Country Club, one of three co-hosting venues.
"I kept it in play all day and I think that`s pretty neat to do around a course like La Quinta," Lahiri said.
"I'm pretty happy with the way I hit it off the tee and didn't miss a green - so that usually does it for you."
Fellow leader 49-year-old Jerry Kelly joined him on the La Quinta Country Club course, while Dufner and Overton played at the Jack Nicklaus Tournament Course.
Dufner hit a 20-foot putt at his final hole to join the leading group - his eighth birdie of the day - with four of his birdies coming in his last six holes.
Defending champion Bill Haas made a rousing start with an eagle on the first hole, before going on to card a six-under 66 to sit in an 11-way tie for seventh.
A group of 13 players shared 18th place on 67.
Meanwhile, a late stumble from Phil Mickelson left him with a four-under 68 for a share of 32nd place, four strokes behind the leaders.
