James Hahn shoots a second-round 65 to move one shot clear of Rickie Fowler and Danny Lee at the Waste Management Phoenix Open.
James Hahn will take a one-shot lead into the weekend at the Waste Management Phoenix Open thanks to a six-under-par second round at TPC Scottsdale.
Hahn's 65 on Friday saw him move to 10-under for the tournament, one shot clear of first-round leader and fellow American Rickie Fowler.
Fowler is joined in second place by Australia's Danny Lee, who carded a five-under 66 to climb up the leaderboard.
Shane Lowry and Hideki Matsuyama were tied for the lead with world number four Fowler, but both fell three shots off the pace with a one-under 70 on day two in Arizona.
