His putter finally cooperating, Adam Scott has surged into contention for a 15th US PGA Tour victory with a scintillating second round at the CJ Cup in Las Vegas.
With two back-nine eagles and seven birdies, Scott carded a nine-under-par 63 to soar to 13 under for the championship to be in a four-way tie for second.
The former world No.1 is level with Americans Jordan Spieth (65) and Harry Higgs (67), and South Korea's Seonghyeon (63).
The quartet trail runaway halfway leader Keith Mitchell by five shots after the American backed up his opening 62 with a 64 on Friday to move to 18 under.
