BBC Sport NI examines a varied result sheet for the division's leading clubs.
The champions secured victory on Friday evening to close the gap to their nearest rivals.
Larne's triumph brought them to within six points of Linfield, who were held to a 1-1 draw by Dungannon Swifts on Saturday.
Their campaign began strongly with six wins and one draw from seven league fixtures.
The margin to Coleraine also shrank to nine points following the Bannsiders' 1-1 stalemate with Duncan Ferguson's Glentoran.
Attention focused heavily on the new manager of the east Belfast side during that match.
It remained unnoticed that this fixture resulted in two points lost for the leaders.
Gary Haveron's team has now dropped points only three times throughout the current season.
They retain a two-game advantage over both Coleraine and Linfield in the standings.
The Bannsiders previously suffered consecutive home losses to Coleraine and Linfield within four days in October.
Joel Cooper scored an early goal against Glentoran before the match ended in a draw.
Coleraine's next fixture is away to Cliftonville on Friday night.
Linfield also drew 1-1 with Limavady United after recovering from being behind against Bangor.
The Blues will seek to recover their deficits while facing further competition this week.
