"The players can enjoy that winning feeling, but we know there's plenty of work to be done but we can move on with a realluy positive frame of mind," he said.
Ever the realist, the Scotsman knows his side aren't out of trouble at the bottom of League Two just yet after a sorry start under Steve Thompson.
"It gives us a five point cushion and now being only five points off twelfth place we can start to look up that league table," he said.
"It's a bit tight in there, but we have to keep battling away and move up the table."
He was also full of praise for matchwinner MacKenzie.
"It was a great finish from Neil. The lads battled and scrapped and fought hard for each other," he enthused.

"They have every right to moan. The only positive is that we kept a clean sheet," he said.
