LOS ANGELES — Austin Cook, chasing a second US PGA Tour title, fired an eight-under par 64 on Saturday to seize a one-stroke lead through 54 holes of the CareerBuilder Challenge in California.

Cook, who captured his first tour title in November at the RSM Classic at Sea Island, Georgia, fired seven birdies and an eagle and rolled in a tough par-saving putt at the 18th at La Quinta Country Club.

He emerged from the third round on 19-under par 197, one stroke in front of fellow Americans Andrew Landry and Martin Piller, who are both seeking a first PGA Tour crown. — AFP
