Jonas Blixt fired a 7-under 64 on Friday to move into a share of the lead with Brendon de Jonge after the second round of the Justin Timberlake Shriners Hospitals for Children Open.
Blixt finished two rounds at 14-under 128 and was joined there by de Jonge, who carded a 5-under 66 in round two. Both Blixt and de Jonge are searching for their first PGA Tour title.
First-round leader Ryan Moore managed a 3-under 68 to finish 36 holes in third at minus-13.
Tim Herron (68) and Daniel Summerhays (63) share fourth place at 11-under-par 131 at TPC at Summerlin.
Last year's runner-up Nick Watney shot 66 for the second straight day. He shares sixth place at 10-under 132 with John Daly (63), Vijay Singh (66), Chris Kirk (68) and John Huh (69).
Blixt stumbled out of the gate with a bogey on the third, when he failed to get up and down from a greenside bunker. He came right back with an 8-foot birdie putt on the fourth.
The 28-year-old Swede made it two in a row as he holed a birdie attempt from off the green on the par-3 fifth. Blixt parred six, then holed out for eagle from 104 yards on No. 7.
Blixt poured in a 26-footer for birdie on the ninth and followed with a 15- foot birdie putt at 10. After a birdie on 13, he 2-putted for birdie on the short par-4 15th and came back with a 2-putt birdie on the par-5 16th to move to 15-under.
However, he gave those two strokes back with a double-bogey on the 17th. His tee ball on the par-3 found water left of the green. After he chipped on, Blixt 2-putted from six feet.
At the last, Blixt sank a 10-footer for birdie and a share of the lead.
"I've been working a lot on my ball-striking the last few weeks when I've been off. It's not really there yet, but I got a hot putter and it's been helping me out a lot the last two days," Blixt stated.
De Jonge started on the back nine and got on the board with an 8-foot birdie putt on the 13th. At the 15th, he made eagle from just off the green and followed with a 4-foot birdie putt on 16 to get to 13-under.
The Zimbabwean came up short at the 18th and that led to his only bogey of the day. He quickly erased that mistake with a 17-foot birdie putt at the first.
De Jonge, 32, ran home a 29-foot birdie putt at the fifth to grab a share of the lead. He parred the last four to end there.
"I've driven the ball well for the first two rounds. With as receptive as the greens are here, you're going to have a lot of chances," de Jonge said. "That's been the key - I've been able to set myself up to score well from the fairways."
Moore stumbled to a bogey on the fourth. He quickly moved to 12-under thanks to three birdies in a 4-hole span from the eighth. Moore parred five in a row before sinking a birdie try at the 17th. He parred the last to end one back.
