Long struggled with a bogey at No. 1, but he more than made up for it with four birdies over his next eight holes. He rattled off five consecutive pars before he rolled in 15-foot birdie putt at the 14th to reach 11-under.
'It was again a beautiful day here and the greens are firm,' said Long, who will be looking for his first win on the Buy.Com Tour. 'It was a matter of patience and I'm just very happy with how patient I'm being out there.'
Hillcrest Country Club is a tough par-71 layout and Long has used irons off the tee more than most players this week in an effort to set himself for placement on the greens.
'I try and do what's best for me and try get on these greens,' he said. 'That's the main thing. Once you get out of position here, it's so hard to get yourself back into position to make pars.'
Judah mixed one bogey and a birdie on the front nine, but climbed up the leaderboard on the back nine. He ran home a 30-foot birdie putt at 11 and made it two birdies in a row with a 12-footer at No. 12. Judah tied for the lead when he snaked in a five-foot, left-to-right birdie putt at the last.
'You work hard to try to win golf tournaments and all you want is an opportunity and I definitely put myself in that position,' said Judah. 'I'm playing well. The first two days I struggled a little bit with my swing and I just putted lights out.
'Something just came on today. I felt it coming on and finally today it started to feel good on the back.'
Overnight leader Jim Benepe posted an even-par 71 on Saturday and is tied with Chad Wright, who fired a 66 in round three. The pair stands at minus-9.
