Jordan Williamson pumps a long ball forward, it's flicked on and McElroy breaks into the area.
He could have hit it early, but he cuts back inside and curls a brilliant effort into the far corner.
It was route one but very, very effective.

Tiernan Lynch makes the first move.
Dean Jarvis, Thomas Oluwa and Lee Lynch come on as Larne make a triple substitution.

Quote Message: As the half went on Ballymena grew into the game. They committed more men forward and on the flip side that afforded Larne more opportunities. I do feel as players start to tire space will open up for the creative players on both sides.
