World No.218 Miguel Tabuena produced the hottest of starts to take a share of the clubhouse lead at the World Super 6 Perth golf tournament at Lake Karrinyup.
Tabuena birdied nine of his first 10 holes on Thursday to open up a huge early lead, before the Filipino settled for a seven-under 65.
He was joined at the top of the leaderboard with Norway’s Kristoffer Reitan, who posted eight birdies and a bogey in a strong opening round.
New Zealand’s Benjamin Campbell is third at five-under, with Nick Flanagan and Brad Kennedy the best of the Australians at four-under.
Rising star Min Woo Lee and fellow local Jason Scrivener settled for solid rounds of two-under.
Tournament favourite Thomas Pieters, who was battling illness on the eve of the tournament, also finished with a two-under 70.
2006 US Open winner Geoff Ogilvy is one-over after eight holes, while Victorian Lucas Herbert shot a disappointing two-over 74.
World No.55 Tom Lewis – the highest ranked player in the field – sits at one-over after seven holes.
Indian SSP Chawrasia shot a strong four-under 68 to put himself into the mix.
But he could only watch on in awe as his playing partner Tabuena lit up the course early.
“Me and Terry Pilkadaris both (were just) looking at each other,” Chawrasia said.
“Every hole he make birdie, birdie, birdie, the first six or seven holes.
“So you know, nine-under after 10 holes – I’ve never seen (that) before.”
The first three rounds of the tournament are traditional stroke play.
The top 24 players will then qualify for the last round match-play, which consists of a series of elimination six-hole shootouts.
If a shootout is tied at the end of six holes, a 90m shootout hole will decide the winner of that duel.
