Gibson added a Saturday 65 to opening rounds of 62-67 to reach 10-under par and join American Kramer Hickok at the top of the leaderboard at the Lincoln Land Championship.
The pair are two ahead of a group of four players with another Australian, Jamie Arnold, among those at 16-under and sharing fourth.
Gibson entered the week 25th on the Web.com Tour money list but is projected to move as high as fourth with a victory.
The top 25 at season’s end are guaranteed status on the PGA Tour for 2019 and after starting the year with back to back third place results Gibson is now all but assured of promotion at the end of the season.
It’s been an impressive week so far for Gibson who has amassed 20 birdies and an eagle against one bogey and one double bogey at the Panther Creek Country Club.
Gibson is playing his third full season on the secondary US circuit where he is yet to record a victory though has three runner-up finishes.
Good play in 2015 earned him PGA Tour status in 2016 but he failed to keep his card on the main Tour and has played the last two years on the secondary circuit again.
He and Cameron Davis are all but assured of graduating this year and a victory tomorrow would be a significant confidence boost for Gibson.
Gibson isn’t the only Australian who has been impressive this week as Sydney’s Jamie Arnold is also in the running for the title.
Arnold is three shots adrift of Gibson and Hickok with one round remaining, rounds of 65-66-67 his best performance in an otherwise pedestrian season to date.
Entering the week 72ndon the money list, Arnold is in desperate need of some good results and quickly if he is to earn PGA Tour status via the end of year money list and a good round tomorrow would go a long way toward achieving that goal.
Curtis Luck was the only other Australian to make the cut but a 2-over third round dropped him to T71.
