LOS ANGELES: Jason Dufner won his first US PGA Tour title since the 2013 PGA Championship on Monday with a tense playoff victory over Sweden’s David Lingmerth in the CareerBuilder Challenge in La Quinta, California. The two had finished 72 holes tied at 25-under 263, four strokes in front of their nearest rivals. Dufner, who started the day with a two-shot lead, missed a 20-foot birdie attempt at the final hole of regulation, signing for a two-under 70 on the TPC Stadium Course at PGA West. Lingmerth, who had stormed into contention with a 62 on Saturday, carded a bogey-free 65. Five-time major champion Phil Mickelson, a two-time winner of this event in the Southern California desert, fired a final-round 68 to share third place with fellow Americans Andrew Loupe and Kevin Na, who also signed for 68s.
