While two new courses have been added to the rotation at the CareerBuilder Challenge, scores remain low amid "golf in a dome" weather conditions. Here is how things look after the first round in Palm Springs, where Jason Dufner headlines a foursome atop the standings:
Leaderboard: Jason Dufner (-8), Anirban Lahiri (-8), Jerry Kelly (-8), Jeff Overton (-8), Andrew Loupe (-7), Colt Knost (-7), Jamie Lovemark (-7), Bill Haas (-6)
What it means: With the field spread across three different courses, the key was piling on birdies early and often.
