'I don't know any other position on this golf course than first,' said Barranger. 'That's where I'm comfortable being. I'm comfortable leading the pack.'
Last year at The Golf Club at Yankee Trace, Barranger amassed a 26-under-par 262 total to match the Buy.com Tour record for lowest score in relation to par. The 33-year-old has continued to score at the venue in search of his second career win.
'I'm very comfortable with this course,' said Barranger. 'It sets up well for me. Where the trouble is, I can either hit it past it or it's not where I normally hit the ball.'
Barranger, part of a five-way tie for the lead following the opening round Thursday, broke out of the logjam thanks to back-to-back birdies to begin the round.
He collected another birdie at the par-three seventh before running into trouble with a bogey at the ninth to make the turn at minus-eight.
Barranger responded with a birdie at the next hole and continued to cruise with back-to-back birdies starting at the 12th. He capped his round with a birdie at the par-five 18th to finish with the outright lead.
'I'm playing good but it's going to be a horse race just like it was last year,' said Barranger. 'It's going to be a birdie festival.'
Buha briefly held a share of the lead thanks to an eagle at the par-five sixth, but a late bogey dropped him back into second.
'I smashed a drive down there and had 211 yards to carry it on the green,' said Buha, referring to the sixth hole. 'I roasted a six-iron. It might be one of the best irons I've ever hit in my life. It rolled up there to within six feet.'
Buha started the day on the back nine and picked up two straight birdies from the 11th. He coasted at even par around the turn until his third birdie of the day at the second. Buha then birdied the fifth before the eagle at the very next hole.
Joel Kribel, one of the first-round leaders, carded a four-under 68 to finish two shots off the lead at 10-under-par 134. Kribel was joined by Tom Carter, who shot a six-under 66.
Bob Friend, Brad Adamonis, Darron Stiles, Todd Rose, Pete Morgan and Chris Couch finished were tied for fifth place at nine-under-par 135.
Aaron Baddeley and Dave Rummells, who were also among the leaders after the first round, managed rounds of one-over 73 to finish seven shots back at five- under par.
The cut fell at three-under-par 141 with 75 players qualifying for the weekend.
