The 20-year-old was unfortunate to be axed from the side which had won 1-0 in the Scottish Cup at Forres Mechanics, given he had scored the winning goal.
But with the more experienced Dean Shiels fit again for Saturday's Third Division match at Stirling Albion, it was the Northern Ireland man who got the nod.
Naismith had to settle for a place on the bench, but came on in the second half of the surprise 1-0 defeat.
Although that was disappointing, he took his frustration out on Airdrie on Monday night as Gers came from behind to win 4-3 at the Excelsior Stadium in the Reserve League.
Naismith played a big part in the win, setting up Andy Mitchell's equaliser then stroking home a penalty and grabbing the winner.
His performance will have caught watching assistant manager Kenny McDowall's eye and he hopes that works in his favour. Naismith said: "It's always good to score but we were 2-0 down against Airdrie and it was good to come back and win.
"It was disappointing to come out of the team on Saturday after I scored the winner against Forres. But I respect the gaffer's decision to bring Deano back in. I just need to keep doing well when I get chances.
"If you let your head go down, the gaffer's not looking for that. He wants a reaction.
"Hopefully I can keep scoring goals, get noticed and work my way back in. I feel confident and like I can get goals, so hopefully I can take that forward into future matches."
