Halfway leader Owen slips back after a 73
American Troy Matteson will take a three-shot lead into the final round of the Frys.com Open after shooting a second successive 61 in Scottsdale, Arizona.
The 29-year-old carded 10 birdies, the only blemish coming with a bogey at 13. His total of 122 for successive rounds broke Steve Stricker's Tour record of 123, set at the Bob Hope Classic in January.
Matteson is bidding for his second PGA Tour victory, and will do so with a three-shot cushion over compatriots Chris Stroud and Webb Simpson, and South African Tim Clark.
A delighted Matteson said afterwards: "With the year I've had, it's - first of all - it's indescribable. Two days ago, if you'd have asked me what I was going to shoot on Friday, I would have said 'I'll take anything in the red'.
"It's amazing how fast golf changes. It's just one day something clicks, and all of a sudden you get on a little run.
"Hopefully I can keep it going. It's nice to have some good rounds with the year I've had. It's getting towards a nice ending."
On lowering the PGA Tour record with stunning back-to-back rounds, he added: "It's just been unbelievable. I've not even shot a 61 prior to this week. To shoot two of them, I don't even know what to say.
"(I'm) just making a lot of birdies out there and hitting a lot of good shots and keeping my ball in play... a lot of close opportunities, and that's really the key out here."
England's Greg Owen, who posted 65 on Thursday and 64 on Friday to share the lead at the halfway stage, slipped back to joint 19th on Saturday after a disappointing three-over 73.
