The South African trio of Erik van Rooyen, MJ Daffue and Branden Grace all failed to make the cut for the weekend at the Sony Open in Hawaii.
Having made respectable starts to their week on Thursday, all three struggled to get going during the second round.
Van Rooyen shot an even-par 70 to remain on three under on Friday, while Daffue dropped down after going three over for his second round.
Grace, in particular, found it tough in Honolulu, carding a second-round 75 to end his participation in the event on four over.
Canadian Nick Taylor leads the way, however, sitting at the top of the leaderboard with a two-shot lead on 12 under par.
Taylor shot a spectacular eight-under 62 for his second round to climb to the top. Five players, though, are in T2 on ten under and will be hoping to challenge for first place over the course of the next two rounds.
Stewart Cink, Webb Simpson, Russell Henley, Vaughn Taylor Chris Kirk are all within touching distance ahead of moving day, with another big group of eight players just a further stroke back.
