Jorgensen fired a 6-under 64 on Thursday to take the lead after one round of the Canadian Tour Championship -- a new season-ending event.
The American mixed seven birdies with just one bogey at Highlands Golf Course, setting a new course record with his 64. He leads three players by four shots heading to the second round.
Not too bad for a player who has finished no better than tied for 18th in eight previous starts this season.
It's a lack of success Jorgensen talks freely about.
'I've played like a dog out here for most of the season,' he said. 'Of course, I'm looking to play good every week, but I'm looking for a good strong finish here.'
Jorgensen had his only bogey of the day at the par-3 fourth, where he three-putted. He still made the turn at minus-3, then set fire to the back nine.
Birdies at 11, 12 and 13 came after Jorgensen knocked approach shots within 7 feet on each hole. He carded four routine pars after that, then saved par at the 18th after blasting to within 3 feet from a bunker.
'I felt great out there,' he said. 'I was positive all day long and committed to all my targets. This is not an easy track.'
One thing Jorgensen didn't do much of was scoreboard-watch.
'I knew where I stood as the day went on, but I try not to look at that stuff. I'm working at a lot of things right now, but watching the leaderboard is not one of them,' he said.
At the end of the day -- had he been looking -- Jorgensen would have seen fellow American Chris Carnahan tied for second place with Canadians Stuart Anderson and Lee Curry at 4-under 66.
Carnahan, who says this will be his final event on the Canadian Tour, might want to think again if he wins. After making just 10 cuts in 31 career starts, he would earn $25,600 with a win this week.
It would be his first.
'I've been at this a long time, I guess it's time for a change,' said Carnahan, who has been on tour three years. 'When you start out like this, you wish every week was just like it. If they were all like this, things might be a little different.'
