BOISE, Idaho -- Russell Knox followed his record-tying 59 with 68 on Saturday to drop a stroke behind Philip Pettitt after the third round of the Web.com Tour's Boise Open.
Pettitt had an 8-under 63 to reach 18-under 195 at Hillcrest Country Club.
"I knew it was going to be a challenge, how can it not be? I had to regroup," Knox said. "I was still close to the lead. I had a bunch of 10, 15 and 20-footers for birdie that went in yesterday but not today. I was expecting it, just like I expect them to go in tomorrow."
The Scot made short birdie putts on Nos. 16 and 17 to get a spot in the final group.
"Everyone is bunched up now and tomorrow is going to be a shootout," Knox said. "I'm in perfect position. They're all going to find it difficult tomorrow to back up their good rounds."
