Dufner leads, Hadwin in third

LA QUINTA, CALIF.— Jason Dufner patiently worked his way around PGA West’s TPC Stadium Course 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. Canadian Adam Hadwin was tied in a group at 12-under after his second straight 66.
