Danny Lee and Reid Edstrom both fired 6- under 66s on Friday to grab a share of the lead through two rounds of the WNB Golf Classic.

Lee, the 2011 champion, was briefly alone atop the leaderboard, but he stumbled to his only bogey of the day on the par-3 16th to drop into a tie with Edstrom at 10-under 134 through 36 holes.

"It's just one of those weeks where things have been working and you've got to enjoy those weeks, they don't happen often," said Edstrom. "I don't think I've missed a putt inside of 10 feet yet. It's been stress-free for the most part."

First-round co-leader Daniel Chopra shot 69 at Midland CC and fell into a tie for third place with Whee Kim (66), Rod Pampling (67), Brian Duncan (68), Brice Garnett (65) and Clodomiro Carranza (67) at 9-under.

Nick Flanagan (68) and Josh Broadaway (69) are tied for ninth at 8-under, while Todd Hamilton (71), who shared the lead with Chopra and Alex Cejka after 18 holes, is knotted in 11th with four others at 7-under.

Cejka, meanwhile, tripped to a 73 and dropped into a tie for 22nd at minus-5.

Edstrom, who missed the cut at the Colombia Championship and tied for 26th last month at the Chile Classic, carded six birdies during his bogey-free second round.

He picked up shots on Nos. 2 and 4, then turned the trick in succession starting at the seventh to wrap up an outward 32. Another gain at the 12th had Edstrom part of a group deadlocked at minus-9, and a birdie on the par-4 last separated him from the pack.

"I kind of sprayed it around a little bit but always seemed to get away with it," said Edstrom. "The trees are so tight generally that if you hit it in there, nine times out of 10 you're going sideways to get it back into play."

Lee, who tied for second place at this event last year, was close behind after a bogey-free opening nine which featured birdies at Nos 1, 4, 5, 7 and 9. He birdied the 12th to pull even with Edstrom and briefly moved ahead with another gain on the 15th, where his tee shot landed in a fairway bunker and bounced out.

"Stuff like that, it just happens all the time for me, which is good," said Lee, who lives at Los Colinas in Dallas. "I'm not a member here but maybe I should be. I might move down here."
