Carshalton Athletic moved to within three points of Bostik League South leaders Lewes on Tuesday night after edging out South Park by the odd goal in five.
The Robins looked to be coasting to victory after goals from Omar Koroma after 48 and 63 minutes sandwiched by a Tommy Bradford effort after 56 minutes.
But it ended up being a nervy finish as Chris Smith bagged a brace for the hosts in the 87th and 90th minutes.
However, the Robins held on and its now ten wins in twelve matches.
Walton Casuals moved into fifth spot after a 2-0 win at Woodstock Park against mid-table Sittingbourne.
Harry Mills broke the deadlock to give the Stags a 57th minute lead from the penalty spot.
Four minutes later, Youseff Bamba made it 2-0.
