While Lisnagarvey, Monkstown and Banbridge have their tickets all but stamped for the EY Champions Trophy playoffs, where the fourth berth goes is anyone's guess.
Glenanne moved back into the mix when they beat incumbents Three Rock Rovers 2-0 on Saturday. It owed much to their foreign arrivals, with South African Shannon Boucher scoring his 23rd goal of the season to get them on the board in the second half. Polish goalkeeper Lukasz Domachowski was excellent throughout. Gary Shaw sealed the deal in the closing quarter.
The result moves the Tallaght side level with Rovers on 19 points with four rounds of matches remaining.
Railway are lurking in sixth place two points back. They felt they could have earned more from their 1-0 defeat to Monkstown in which Andrew Ward's first-quarter goal, off the back of some Jonny Bruton magic, was all that stood between the teams.
At the bottom Cookstown's incredible run of form has seen them move out of the relegation places for the first time since October thanks to a 4-0 win over Cork C of I. The Co Tyrone side now have 10 points from their last five games to lift them from being seven points adrift of safety. Ryan Millar's double played a big role, while Simon Todd and Jon Ames also chipped to inflict further misery on a Cork side which has not won since October.
Lisnagarvey are a win away from winning the regular season crown after their 3-2 win over Pembroke; Banbridge strengthened their playoff hopes with a 5-2 win over Annadale.
