Jamie Lovemark and Jhonattan Vegas share the clubhouse lead after the second round of the Zurich Classic of New Orleans was suspended due to bad light.
Lovemark's six-under-par 66 is the low score of the round so far and that took him to 11-under alongside Venezuela's Vegas (69).
Vegas shot an eight-under 64 on day one to share the early lead with Brian Stuard, who is one behind the leading duo but still has six holes to complete today.
World number one Jason Day, meanwhile, is at five-under with eight holes to play.
England's world number 10 Justin Rose, after a pair of level-par 72s, is due to miss the cut (-2) at the tournament he won last year.
