Play has been suspended before the completion of the first round of the Barclays at Liberty National with Kevin Stadler leading the field by one shot.
The 33-year-old shot a bogey-free seven-under round of 64 in New Jersey, which included five birdies in the front nine alone.
Henrik Stenson continued his dazzling late-season form with a 65 to see him trailing Stadler, along with Ryan Palmer and Camilo Villegas.
Jason Day and Matt Kuchar are tied for fifth on five-under.
Despite suffering from a bad back due to a soft hotel bed, Tiger Woods is among a group of seven players on four-under-par, with US Open champion Justin Rose a shot further back.
Harris English (-4) and Marc Leishman (-3) are yet to complete the front nine in their first rounds.
Meanwhile, Ian Poulter (-1), Rory McIlroy (E), Graeme McDowell (E), Luke Donald (E) and Sergio Garcia (E) all posted solid numbers, while Brandt Snedeker (+1) and Lee Westwood (+2) came in over par.
