Rising star Cassie Porter has placed a stranglehold on the women's Vic Open and will take an imposing five-shot lead into the weekend action at 13th Beach.
For the second straight day, the 20-year-old outshone her accomplished playing partners Jiyai Shin and Karrie Webb, both of whom are multiple major winners and former world No.1s.
The highlights of Porter's round of 9-under 64 on Friday were eagles at the par-4 5th - when she holed out with a wedge from 75 yards - and the par-5 18th on The Creek Course.
"On the fifth, I hit it and Amber my caddy and I both said, 'Sit down, that is so far over' but it took one hop and went in," Porter said.
"I couldn't see it but I heard the crowd."
Porter was an astonishing 15 under the card after two rounds, two shots better than the best winning totals of 13 under - by Mel Reid in 2017 and Hannah Green in 2022 - since the women's Vic Open went to a 72-hole tournament in 2013.
First-round co-leader Pavarisa Yoktuan from Thailand (68) was in outright second at 10 under, a shot clear of England's Holly Clyburn and American Emma Talley.
Korean star Shin (71) was in fifth spot at 7-under 138, while the 48-year-old Webb wound back the clock and moved up the leaderboard to 4-under 141 after signing for a 69.
But they were both put in the shade again by Porter, who only turned professional 14 months ago.
"I stuck to my game plan and it came off today," she said.
"You've got to take it when it comes, because it doesn't come very often.
"(Shin and Webb) are amazing players.
"When you're in a group like that and everyone is playing well you kind of feed off it and I did that so I was really happy with myself.
"Putting a score like that on the board is pretty cool."
After shooting the lights out in the morning, Porter had a relaxing Friday afternoon planned on the Bellarine Peninsula before getting back to business.
"I'm trying not to focus on the lead going into the weekend because I've still got another two days of work to do," she said.
"I'm actually going for a quick hike around the beach.
"There's a headland I really want to go and see.
"And then maybe go for a swim, dinner and a snooze."
