Cliftonville manager Tommy Breslin may have made a raft of changes but there was no complacency from the Reds at the Oval.
Goals from Paddy McNally and Stephen Garrett (2) helped Breslin’s side record an impressive 3-0 victory over Glentoran.
The Solitude club earned a thundering win to book their place in the semi-finals of the County Antrim Shield.
Defender McNally opened the scoring with a header from a Chris Curran corner just before the break.
Garrett doubled the lead on the hour mark before putting the game out of sight with a third goal three minutes later.
