Matt Dunstone took three wickets.
Abbots slipped to 43-4, before Bradley Finch (47) and skipper Matt Parkins (32) steadied the ship to leave Abbots needed seven runs off the last four overs. But they lost three quick wickets, with Abbots needing four runs off the last five balls.
Anish Khiroya ran a two and then a single off the penultimate ball, leaving Nixon to face the last ball.
He connected to split two fielders to take the winning run.
