Sion Swifts Ladies and Cliftonville Ladies will contest the Women's Premiership League Cup final for the second successive year.
Holders Sion continued their defence of the trophy courtesy of a narrow defeat of Crusaders Strikers at Seaview.
Sion came close to opening the scoring after Zoe McGlynn played Cora Chambers through on the right side of the box but her goalbound effort was denied by Maddy Harvey-Clifford's outstretched right foot.
Chambers proved to be a threat again after tussling with Caitlyn Hamilton and Beth Chalmers before the ball fell for Chloe McGlade to fire over from 12 yards out.
But Chambers eventually got her reward on 38 minutes after collecting a Kelly Crompton throw-in down the right before creating space to beat Harvey-Clifford low into the bottom right corner from the edge of the area for what proved to be the only goal of the game.
Cliftonville, runners-up last year, swept to a crushing victory over Linfield Women at Solitude.
Toni Leigh Finnegan opened the scoring for the Reds on 21 minutes, sweeping home a free kick from 25-yards out after Vicky Carleton had been fouled.
Marissa Callaghan doubled their advantage seven minutes later, finishing at the back post with Caitlin McGuinness adding a third before the break with a well taken effort.
Abbie Magee further extended the Reds’ advantage shortly after the break when her long range shot clipped the crossbar and bounced over the line.
Keri Halliday then pulled a goal back for Linfield on 54 minutes, racing through on goal before finishing past Rachel Norney.
Fi Morgan ensured the home side regained their four goal cushion as she planted a header into the far corner from a Finnegan free-kick delivery.
Nine minutes from time Carleton, against her former side made it six. She was fouled in the box before slamming home the resultant spot kick to ensure the Reds’ passage to another cup final.
