Brendan Steele and Cameron Davis share the lead at the half-way stage of the Sony Open in Hawaii.
Steele birdied five of his last six holes - the run ruined by a double bogey on the sixth - while Davis made five gains and a bogey as both players recorded 66s during day two to lie on six under.
Graeme McDowell carded a 69 and stands at level par.
Scotland's Russell Knox moved himself into contention with a second-round 65.
The 34-year-old recorded six birdies and a bogey to move to within a shot of the leaders and join a list of nine players on five under. They include major winner Keegan Bradley and overnight leader Collin Morikawa.
Bradley had five birdies and a bogey in a 66 while fellow American Morikawa birdied the last two holes for a level-par 70.
