LA QUINTA, Calif., Jan. 18 (UPI) --
Roberto Castro and James Hahn maintained a share of the lead Friday on another day of extremely low scoring at the Humana Challenge.
More than two-thirds of the 156-player field broke 70 over the three courses used for the tournament with Castro and Hahn tied for the top at 14-under 130.
Castro shot a 67 over the PGA West Palmer Course and Hahn, trying to become the second rookie in as many weeks to win on the tour, also had a 67 at the LaQuinta Country Club.
They had a one-shot lead over Darron Stiles, Scott Stalings and Richard Lee, all of whom fired a 65 in the second round Friday.
Among the group at 132, tied for sixth, were Zach Johnson, Charles Howell III, Aaron Baddeley and Jason Kokrak, who had been tied for the lead with Castro and Hahn when the round began.
Russell Henley, who won last week in his debut as a tour member, was among those at 133. Stewart Cink and Ricky Barnes were also at that number.
Phil Mickelson, playing for the first time this year, shot a 67 at the PGA West Nicklaus Course for a 139 total, but that was good only for a tie for 91st place.
Mickelson will need a low round Saturday to make the 54-hole cut. The survivors will then play the final round Sunday over the Palmer Course.
This tournament is known for its low scores, a tradition highlighted by the 59 David Duval shot in the final round to win the event 14 years ago.
