Selston continue to head the top of the Central Midlands League Black Dragon Badges South Division — and probably had the points won against visitors Keyworth United before half-time.
Ben Moore’s penalty gave them a 12th minute lead before second-from-bottom United were reduced to ten men after an early red card.
Moore doubled the lead in the 26th minute played and Wayne Cooke and Kane Hempshall put Selston four up with just over half an hour played.
Elliot Jones added another five minutes from time as Selston, who have three matches left, preserved their one-point advantage over Eastwood Community and have a game in hand.
Eastwood beat Mickleover RBL 4-1.
Blidworth Welfare lost 2-0 at home to Holbrook St Michaels, who moved out of the bottom two.
