David McKenzie takes a commanding lead into the final day of the Victorian PGA after an impressive third round at Huntingdale.
The Victorian veteran is 15 under through 54 holes, and his pace has proved too much for the pack headed by New Zealander Brad Shilton, who finished Thursday at 11 under.
Defending champion Aaron Townsend is third at 10 under after signing a 71.
But the question is whether anyone in the final groups can catch McKenzie on Friday.
"I have been there (before) but not that many times (holding a big lead)," said the 48-year-old, who won the event in 2013.
"This is a thinking man's course and I have a plan to play it. The key is staying patient and taking your opportunities.
"In saying that, I will assume someone is going to make a run early. So that means taking care of my business so I'm not in a dogfight towards the end."
McKenzie began the third round two shots in front of playing partner Shilton but quickly extended his lead to six after making five birdies on the front nine.
His inward half of 37 was less spectacular but good enough to keep his closest challengers at bay.
