Afghanistan batted first yesterday and were all bowled out for a measly 144 runs in the 39th over.
Mohammad Shahzad top scored with 29 runs.
Barras bowler Norman Vanua did the damage taking 4/36 off his 7 overs which included two maidens.
The Barrras first innings at the crease started off disastrously losing opener Tona Ura (7) and then Lega Siaka for a duck which had them at 2/24.
But Vani Morea (29), Sese Bau (34) and the ever reliable Assad Vala (62) got the run chase back on track.
The Barras finished after stumps on day one at 6/205 after 49 overs with Mahuru Dai (67) and John Reva (0) not out.
Day two will resume play at 9:45am (3:45pm PNG time).
