Carrick Rangers 0-4 Coleraine
Curtis Allen's hat-trick helped Coleraine hammer struggling Carrick in the Carling Premiership encounter.
Paul Heatley was off-target from a couple of Carrick chances before Gareth Tommons' cross-shot flew into the net over Carrick keeper Maros Valko on 17.
A Valko mistake allowed Allen to double Coleraine's lead on 30 and the striker added the Bannsiders' third on 39.
Allen completed his hat-trick on 58 and Carrick's Stephen O'Neill was sent-off after his second yellow card on 61.
Carrick made a promising start at Seaview with Heatley causing early difficulties for midweek Coleraine signing Ruairi Harkin.
Heatley manoeuvred himself into threatening positions on two occasions but was off-target with his first chance and saw his second effort cleared by Howard Beverland.
The Bannsiders took the lead in their first serious attack as Tommons' cross-shot flew in over the Carrick keeper.
Valko then did well to touch an Allen shot onto the woodwork but the Carrick keeper was at fault for Coleraine's second goal as he dropped a cross which allowed Allen to tap into the empty net.
The game was over as a contest nine minutes later as Allen glanced in at the far post.
Allen completed his hat-trick on 58 minutes as he hammered to the net after yet more indecision in the Carrick defence.
Carrick's woes increased as striker Stephen O'Neill was sent-off by referee Hugh Carville after two yellow cards in quick succession for dissent and a heavy challenge on Johnny Watt.
The win extends Coleraine's unbeaten league run to nine games.
