Mark Smith kept his second clean sheet in four games as Hampton & Richmond upset the league leaders Margate 2-0 at The Beveree on Saturday.
The Beavers, who had won only once in their last four league games, took the lead just before half-time through Charlie Moone.
Mark, making his fifth appearance for the Ryman Premier side since joining on loan last month, made a number of fine saves in the second-half to keep Margate at bay before Nicholas Bignall settled things late on.
The result lifts Hampton up to 14th in the table ten points off the play-off places and ten points above the relegation zone.
Will Grigg played the final 20 minutes as MK Dons recorded a 1-0 win at home to Port Vale to move up to fourth in Sky Bet League One.
Carl Baker was the match winner for The Dons, scoring after three minutes, as Karl Robinson's side recorded their third straight win in all competitions.
Saturday's appearance was Will's 18th for MK where he is on a season-long loan, scoring six goals.
