Brendan Jones fired a 7-under 64 in the third round and is tied for third place with Mike Springer, who shared the second-round lead with Points. Springer shot a 69 on Saturday and is tied with Jones at minus-12.
Points was 5 under through 13 holes and opened a commanding lead over the field. He came back thanks to three bogeys over his final five holes, including a six at the par-5 closing hole.
'I'm still tied for the lead,' said Points, who won the 2001 Inland Empire Open. 'If someone would have given me 3 under before the round I would have taken it.'
This marks the second consecutive year that Points held at least a piece of the 54-hole lead at this event. Last year, he struggled to a 3-over 74 and finished three behind eventual winner Andre Stolz.
'Tomorrow I think I can come out and shoot 5 or 6 under and hopefully close the door,' said Points. 'I'm prepared. I've played so much golf in the last couple of weeks.'
Wilson was 1 under through his front nine, but vaulted up the leaderboard with three birdies in a four-hole span from the 11th. He parred his final four holes and is in position for victory No. 1 on the Nationwide Tour.
'I'm in good position heading into the final round,' said Wilson, whose best finish on tour was a tie for eighth at the 2002 SAS Carolina Classic. 'I haven't been in this position in a while so tomorrow will be exciting.'
Fran Quinn and Mathew Goggin each shot rounds of 3-under 68 and are tied for fifth place at 11-under-par 202. Scott Gump (65), Scott Petersen (66), Brett Wetterich (69) and 2002 U.S. Amateur Champion Ricky Barnes (69) share seventh at minus-10.
