Naomi McLaughlin and Demi Vance each struck twice as Glentoran Women overwhelmed Larne Women 7-1 at Larne Academy of Sport.
The visitors needed only seven minutes to go in front through Aimee Kerr. McLaughlin doubled the advantage three minutes later and Mia Moore made it 3-0 in the 13th minute.
Emily Wilson added Glentoran's fourth after 23 minutes before Vance converted from the penalty spot on the half-hour, completing a five-goal opening period for the visitors.
Vance scored her second penalty in the 56th minute and McLaughlin completed her own double on 86. Chloe Tully replied for Larne in the first minute of stoppage time.
Glentoran had also beaten Larne 5-0 at Blanchflower Stadium in May, leaving the Glens with a 12-1 aggregate score across the clubs' two Women's Premiership meetings this season.
Glentoran next visit Lisburn Rangers, while Larne's next scheduled league fixture takes them to Crewe Park to face the same opposition on 28 August.
