Jonathan Caldwell narrowly made the cut at the Scandinavian Mixed but Olivia Mehaffey missed out on the weekend after Friday's second round.
Down native Caldwell, who earned his first DP World Tour win at the event last year, had opened with a 71 on Thursday at the Halmstad Golf Club in Sweden and replicated that score on Friday to make the cut by a shot on two under.
He is 10 shots adrift of Australia's Jason Scrivener who leads the way on 12 under after a 64.
Scrivener holds a two-shot advantage over Carolina Melgrati, Linn Grant and Michael Lorenzo-Vera.
Royal County Down golfer Mehaffey finished on four over after her second round 77, having opened with a 71 on Thursday.
