Glentoran took advantage of Cliftonville not playing on Monday night to close the gap at the top of the Danske Bank Women’s Premiership to two points.
A double from striker Kerry Beattie – who has returned to the Glens following a stint at Glasgow City – helped Billy Clarke’s side to a four-goal victory at Lisburn.
The Northern Ireland international grabbed a goal in either half while captain Jess Foy was on target after the break, before Casey Howe added a late fourth at the Bluebell Stadium as the defending champions moved to within two points of Cliftonville, who now have a game in hand.
There was also a four-goal victory on the night for Linfield, who leapfrogged Crusaders Strikers into third spot thanks to a comfortable win at Mid Ulster.
Rebecca Bassett gave the Blues a fifth-minute lead before Rachel McConnell doubled the advantage ten minutes before the break.
The visitors added a third before the hour mark after Abi Sweetlove’s initial effort was blocked before, Emily Reid added a fourth with three minutes remaining to complete the Linfield win.
