Northampton dominated the early stages and Andy Kirk headed them into the lead from Ian Henderson's cross.

Roberts equalised from the spot after Colin Larkin handled in the box and then he almost gave Swindon the lead when his shot bounced off the post.

But it was Northampton who had the best chances to win it with Andy Holt and Paul Hubertz denied by Phil Smith.
