Gary McCutcheon's superb long-range lobbed goal was the highlight as Crusaders maintained their fine home record by beating Glentoran at Seaview.
McCutcheon spotted keeper Elliott Morris off his line and beat him with a great chip from just inside the Glentoran half in the 25th minute.
That made it 1-1 after David Howland's opener for Glentoran who soon regained the lead through a Mark Clarke header.
Declan Caddell and Eamon McAllister's goals sealed the win after the break.
Caddell netted a back post header in the 67th minute and former Donegal Celtic midfielder McAllister beat Morris with a fine drive.
