Hudson Swafford and Boo Weekley share the lead after the second round of the Zurich Classic of New Orleans was suspended on Friday.
Swafford carded a six-under 66 at the TPC Louisiana to move into 11 under at the PGA Tour event.
The American is alongside his countryman Weekley, who was three under through 15 holes before the round was suspended due to inclement weather.
A group of five players – Jason Day, Brendon de Jonge, Cameron Tringale, Jerry Kelly and Daniel Berger – are locked at 10 under.
Only De Jonge and Tringale have completed their rounds of that quintet.
Swafford went through bogey-free, setting his round up with birdies on the first, fourth and seventh holes, before another three on the back nine.
Joint overnight leader Weekley had holed three birdies before his round was cut short with three holes still to play on the front nine.
De Jonge, who like Weekley had produced an opening-round 64, carded a 70 – while Tringale's 65 included an eagle at the par-five second.
The weather halted Kelly's momentum.
The American produced four consecutive birdies starting at the 13th, but bad weather meant he still has a hole to play.
Berger was four under through 15 holes and Day five under through 14.
In a tie for eighth at nine under are Americans Chad Campbell (68), Morgan Hoffmann (five under through 15), Justin Thomas (five under through 12), Chris Stroud (four under through 11), as well as Australian Steven Bowditch (five under through 15) and Canadian David Hearn (two under through 11).
