Boo Weekley and Brendon de Jonge fired 8-under 64s on Thursday and share the lead with the first round of the Zurich Classic of New Orleans suspended due to darkness.
Weekley, who is making his 225th PGA Tour start, is a three-time winner on the PGA Tour, while de Jonge is searching for his first tour title.
Sean O'Hair was 6-under par through seven holes at the TPC Louisiana. He played the final 11 holes in 1-under for a 7-under 65. O'Hair shares third place with David Hearn.
Erik Compton, Brian Davis, Daniel Berger, Mark Hubbard and Greg Owen are one stroke further back at minus-6. World No. 6 Jason Day and No. 7 Dustin Johnson are among 12 players tied for 10th at 5-under 67. Day and Johnson are the two highest ranked players in the field this week.
There was a 78-minute delay due to heavy rain, which pushed play back. The first round will resume Friday at 9 a.m. ET, while the second round will start as scheduled at 8 a.m.
