Emelia Bartram returned figures of 3-6 and Carla Wood hit 51 as Oxfordshire set-up a promotion play-off match in the ECB Women's County Championship.
Oxon won their divisional play-off clash against Suffolk at Milton Keynes by four wickets, meaning they go on to face Cambridgeshire & Huntingdonshire tomorrow when a win will see them promoted to Division 3.
Choosing to bowl first, Bartram’s early spell had Suffolk on the back foot at 24-4.
But after their middle order threatened to re-build their innings, Lucy Gladdy took two quick wickets as Oxfordshire bowled out their rivals for 105.
A disastrous start saw Oxon slump to 4-3, but Wood led the recovery, helped by Gemma Muttitt, Bartram and Suzy Halsey as they passed their total with 15 overs to space.
