Per the usual, the layouts at the CareerBuilder Challenge yielded several red numbers on Thursday. And it's created a logjam at the top.
Four players finished the first round in La Quinta, Calif., tied for the lead at 8 under. Among the three-course rotation over the first three rounds will be La Quinta Country Club and PGA West's TPC Stadium Course and Jack Nicklaus Tournament Course. But only the Tournament Course and La Quinta were represented amidst the early leaders.
Jason Dufner, Jerry Kelly, Jeff Overton and Anirban Lahiri represent the four leading at 8 under, with two more at 7 under and another 10 at 6 under.
