Jason Scrivener made a surge up the leaderboard on a frantic third day of the ISPS HANDA World Super 6 Perth, as the field battled to make it into the match play stages at Lake Karrinyup Country Club.
The top 24 at the end of 54 holes were set to advance to the six-hole match play knockout stage on Sunday, with the top eight finishers receiving a bye into the second round.
Australian Steven Jeffress turned in 33 to lead the way at 13 under but home favourite Scrivener and Canadian Austin Connelly were the big movers, both jumping 13 places on the leaderboard as they looked for a bye on Sunday morning.
Scrivener was five under for his round after 15 holes, with Connelly also picking up five shots in 13 to sit at 11 under and in a share of fourth.
The Australian - a Qualifying School graduate in both 2014 and 2015 - made birdies on the fifth, ninth, 11th and 12th, and when he holed a five-footer on the 15th, he was in that all-important top eight.
Connelly was also bogey-free for the day, picking up shots on the fourth, sixth, ninth, tenth and 11th.
At the top of the leaderboard, Jeffress had birdies on the fourth, sixth and seventh to sit at 13 under, a shot clear of countrymen Lucas Herbert and Brett Rumford.
Rumford had held the overnight lead but started with a bogey and after picking up a shot on the sixth, a double-bogey on the next had him drifting out of the top eight places before a birdie on the ninth steadied the ship.
Herbert drove the first to set up an eagle from eight feet but a double-bogey on the second saw him drop straight back to nine under where he had started. Birdies on the sixth, seventh and ninth then gave him a three-shot cushion in the race for a bye.
Daniel Fox had three birdies in his first ten holes to sit at 11 under alongside Connelly, Scrivener and David Bransdon, who was level par for the day.
Jake Higginbottom and Adam Blyth were then in a share of eighth, with a count back set to separate any players level at that mark at the end of play.
Pep Angles, Adam Bland, Nick Cullen, Ryan Evans Mark Foster, Louis Oosthuizen and Johannes Veerman were then at nine under, with Taylor MacDonald, Thomas Detry, Charlie Ford, Hideto Tanihara, Ryan Fox, Casey O'Toole, Duncan Stewart, Josh Younger and Sebastian Heisele right on the bubble for the top 24.
