The 27-year-old claimed the prize for his second goal during the Shrimps’ 4-3 defeat against AFC Wimbledon on September 11.
With the match level at 2-2, Stockton stunned everyone at the Mazuma Stadium by turning and lobbing Dons’ keeper Nik Tzanev from long range.
The goal saw him claim 53 per cent of the public vote held via Twitter.
Stockton said: “A few people have tried to wind me up and say ‘great cross’ and stuff like that but their goalkeeper had been off his line all game.
“If you look at the video of the goal, I have a little look up to try and see where he was and I just saw glimpse of the keeper’s jersey on the edge of the box.
“That goal was the game after being presented with the player of the month award for August, so I knew that I had to back it up and thankfully I did.”
Also nominated were Fleetwood Town’s Danny Andrew for his goal in their win at Rotherham United and Portsmouth’s Ronan Curtis after his effort in their draw with Charlton Athletic.
Stockton’s nine league goals had previously seen him named as League One’s player of the month for both August and September.
He was also named yesterday as the PFA Vertu Motors fans’ player of the month for September.
