D.A. Points matched the course record with a 10-under 62 on Friday and is tied for fourth place with Zoran Zorkic (68) and Bobby Gage (66) at 11-under-par 133.
Boros tallied six birdies and two bogeys through 12 holes at The Golf Club at Yankee Trace but caught fire at the end of the round. He closed with four birdies in his last five holes to best the previous 36-hole mark by two strokes.
'I'd like to get out as far as I can,' said Boros, who won the Lake Erie Charity Classic at Peek 'n Peak Resort this season. 'Friday doesn't mean a whole lot.'
The four-shot advantage after 36 holes equals the largest lead at the midpoint in a Nationwide Tour event in 2003.
Ogilvie, the tour's only two-time winner this season who can earn an automatic promotion to the PGA Tour with another victory, collected six birdies for his round of 66. This was Ogilvie's second consecutive round without any bogeys.
Price put up his second round of 6-under 66 in as many days.
Points was only 1-under through six holes but recorded six birdies and two eagles until his 18th, the ninth at Yankee Trace. At No. 9, Points hit a horrible approach and left with his second bogey of the round but still managed to match Michael Clark's 1999 course record.
'I have to admit that at the beginning of the week I thought a 59 was do-able,' said Points. 'I stood on the ninth tee thinking I was going to make birdie and shoot 60. Then I tug that second shot from the fairway, get too aggressive on the chip and miss the putt for par. All in all, 62 with two bogeys is still pretty good.'
Zach Johnson (68), Steve Gangluff (66), David Morland IV (65), Ryan Palmer (68) and Bob Heintz (67) share seventh place at 10-under-par 134.
The 36-hole cut fell at 5-under-par 139, which was a tournament record, and 62 players advanced to the weekend.
