Colin Little's brace ensured Altrincham rounded off a superb week with a first away win of the season at Weymouth. Having thumped relegation rivals Cambridge 5-0 in midweek, Little's fine strike on the stroke of half time put his team on their way.
And with just under 20 minutes left, Little headed in Peter Band's flick to secure the points for the visitors.
Nick Crittenden had earlier rattled the crossbar for Weymouth, who grabbed a late consolation through Nade.
