David Larmour was the hat-trick hero for Crusaders

Stephen Shaw, Davy Munster, Larmour and Ciaran Gargin had chances before the former Linfield striker headed home Stephen Shaw's corner from close range.

After his 43rd minute opener, Larmour scored his second with a glancing header from Shaw's cross and the forward then had an effort ruled out.

Larmour danced past a couple of defenders and thumped the ball home on 77 and Colm Kearney scored after 83.

Shaw hit the crossbar early on, Paul Hamilton had to clear off his line and Chris Keenan made good saves to deny Shaw and Munster.

Larmour blasted over from eight yards, Gargin was off target with another chance before Larmour opened the scoring.

Kearney had a couple of opportunities for Larne before the hat-trick hero grabbed his second and then had an effort ruled out for offside.

After the Crues' third, Kearney took advantage of a bad mistake by Neil Armstrong to net a late consolation.
