Larne showed their title credentials as they brushed aside Ballymena United to open up a six-point gap at the top of the league.
The Invermen never looked in any serious threat of not taking advantage of their game in hand over their title rivals after Lee Bonis fired them in front in the 40th minute.
It got even better in the second half as a Ryan Waide own goal and a clever finish from Andy Ryan sealed a deserved win for the visitors.
