Welling United 1-2 Alfreton Town
Shaun Harrad scored on his Alfreton debut as his side continued their promotion push with a win at Welling.
The striker, who joined from Bury earlier this month, netted the winner from the penalty spot after John Akinde had been fouled in the box.
Earlier, Harrad's backheel had set up Josh Law to put the visitors in front.
Kurtis Guthrie levelled, turning in Ross Lafayette's cross, but Harrad's spot-kick kept Nicky Law's side in third position in the table.
