Jason Dufner patiently worked his way around PGA West's TPC Stadium Course on Friday to take the lead in the CareerBuilder Challenge.

Dufner shot a 7-under 65, matching the best round of the first two days on the difficult course that is being used in the tournament for the first time since 1987. Jamie Lovemark was a stroke back after a 65 on the adjacent Nicklaus Tournament Course.

Dufner parred the final four holes, escaping trouble on the par-5 16th. The 2013 PGA Championship winner played the front nine in 6-under 30, bogeyed the 10th after hitting into the water, and added birdies on 12 and 14.

Dufner had a 15-under 129 total. He opened with a 64 on Thursday on the Nicklaus Course, will play La Quinta on Saturday, and return to the Stadium Course for the final round Sunday.
