LAS VEGAS (AP) - Kevin Na and Charlie Wi joined first-round leader Jhonattan Vegas at 12-under 130 on Friday to share the lead after 36 holes of the Justin Timberlake Shriners Hospitals for Children Open.
Vegas, the rookie from Venezuela who won the Bob Hope Classic in January for his first PGA Tour title, was tied with William McGirt at 8-under 63 after the opening round at TPC Summerlin in the first of four Fall Series events.
Vegas followed his bogey-free first round with a 4-under 67 that included an eagle and four birdies. He eagled the 286-yard, par-4 15th.
"I felt like I putted really well today," Vegas said. "My ball-striking wasn't as good as it was yesterday, and that's kind of why the round wasn't as good as yesterday. But my putting has been pretty (good), which (is) what I've worked for. And hopefully I can continue that for two more days and we'll be right there where we are."
Na reversed Vegas' totals by following his opening 67 with a bogey-free 63 that featured eight birdies, seven of them in his final 10 holes.
"I was just hoping to make some putts today because I was hitting the ball really well," Na said. "Yesterday, I hit it really well. I felt like I could have scored better, and today the only difference was I was making putts."
Wi, who was a stroke back after the first round, had six birdies in a 66.
"I've had a pretty up-and-down year and I want to go out with a bang; make sure my game is ready for next year," Wi said. "I worked really hard the last three weeks, so I want to perform well for myself the next three weeks, and I want to carry that into 2012."
Brendan Steele, Kris Blanks and Tim Herron were one stroke behind the leaders.
At 132 were Hunter Haas, who had a course-record, 10-under 61 on Friday, Scott Piercy (65), Kevin Streelman (66), Paul Goydos (66), Billy Horschel (66), McGirt (69), Boo Weekley (65) and Nick Watney (67).
Play was suspended for 40 minutes because of lightning near the course and was halted again later with one player, Fran Quinn, having one hole to play. Quinn, who was 3-under, was expected to resume play at 7:45 a.m. PST on Saturday and the cut would be determined then.
Haas' round included an eagle, nine birdies and one bogey and it matched the course record held by Davis Love III (2001) and Tag Ridings (2004).
Defending champion Jonathan Byrd was at 5-under 137 after a second-round 66.
