Scott Langley: Back at the top 
 
 
Langley  led the way on the opening day at the Waialae Country  Club before  Henley claimed a two-shot lead on Friday evening, but the  former made  his move on Saturday to join his American compatriot at the  top. 
The duo will be the final pair to tee off on Sunday as they stand  on  17-under-par 193 - a tournament record through 54 holes. They also  have  a chance to become the first rookies to win in their PGA Tour debut   since Garrett Willis at the 2001 Tucson Open. 
Starting the day two shots behind, Langley made six birdies on  the  first 13 holes to edge ahead before a bogey on the 14th brought him   level with his playing partner again. 
However, he regained the lead with another birdie on the next  hole and  finished with a five-under 65 while Henley two-putted from 30  feet for  birdie on the last hole to finish with a three-under. 
"Whatever happens tomorrow, I'm going to learn from it," Henley said. 
"I've played great golf and I feel like I can compete out here.  Win  this tournament or not, it's already been a very successful week." 
Tim Clark produced another steady round as the South African  carded his  third successive four-under to find himself in third place at  14-under  while Charles Howell III and rookie Scott Gardiner are another  shot  behind. 
Australian Gardiner, another rookie who is making his first Tour start at the age of 36, is delighted to be in with a shout. 
"It's amazing what happens when expectations are not there," he  said.  "I only hit balls once in the two weeks before the tournament  because  we had snow at Christmas and a couple days after." 
Matt Jones, Danny Lee, Pat Perez, Chris Kirk are tied for sixth  at  12-under while 2011 PGA Championship winner Keegan Bradley is at   seven-under.
