Santiago, Chile (SportsNetwork.com) - Craig Barlow carded a 5-under 66 in Saturday's third round and moved one stroke clear of the field at the Chile Classic.

Barlow, who missed the cut in his four previous starts this season on the Web.com Tour, finished 54 holes at 16-under-par 197. He will go for his first tour win on Sunday.

Wes Roach and Dawie van der Walt, two of the three second-round co-leaders, both shot 3-under 68 on Saturday. They are tied for second at minus-15.

Blake Drewitt, who shared the lead with Roach and van der Walt, managed a 2- under 69. He was joined in fourth place at minus-14 by Alex Aragon (67) and Erik Barnes (65).

Jamie Lovemark (68) and Hao Tong Li (66) share seventh place at 13-under-par 200 at Club de Golf Mapocho.

Barlow trailed by one to start the day. He converted back-to-back birdies at the second and third to move to minus-13. After a par at the fourth, he birdied the par-4 fifth.

The 42-year-old made it to in a row as he also birdied the sixth. Barlow ran off four straight pars from No. 7.

Consecutive birdies at 11 and 12 gave Barlow the lead at minus-17. He tripped to a bogey at the 14th, but atoned for that mistake with a birdie on the 16th. Barlow faltered to a bogey at the par-5 closing hole to trim his lead to one.

"The wind got progressively worse as the day went on. It's the real deal right now," Barlow said. "I'm hitting a lot of fairways and a lot of greens and making a lot of 10-, 12- and 15-footers that you've got to make. I played super today despite that last one."

Roach opened with a birdie at the first, and followed with three pars in a row. He soared into the lead at minus-16 with three birdies in a 4-hole span from the fifth. Roach had eight pars and a bogey on the back nine to post minus-15.

Van der Walt birdied the first and third, but stumbled to a bogey at the fourth. He erased that mistake with a birdie at No. 7.

Around the turn, van der Walt birdied three of the first six holes to jump into the lead at 17-under. However, the South African bogeyed the final two holes to fall one behind.
