Jason Dufner Leads the CareerBuilder Challenge by One Stroke After Round 1

With the field spread across three different courses, the key was piling on birdies early and often. Overton was the first to turn in a 64, but he was quickly joined by the globetrotting Lahiri, 49-year-old Kelly and Dufner, who is still in search of his first win since the 2013 PGA Championship.  Jason Dufner had the best round of the day teamed with Brandt Snedecker  to win last month's Franklin Templeton Shootout, and that momentum was evident in Thursday's opener.  Lahiri spent last year traveling the world as he pursued cards on both the PGA and European Tours. He accomplished that goal, then took a big step toward a breakthrough win with his bogey-free 64 at La Quinta Country Club. The Indian's round included eight birdies, highlighted by three in a row on Nos. 11-13. Zach Johnson is one of the highest-ranked players in this week's field, but he has some work to do after a 1-over 73 at La Quinta. Johnson's round included an eagle, two birdies and five bogeys as the reigning Open champ followed his eagle on No. 13 with three straight bogeys. Who is your pick to win this championship?
