Morton 0-2 Ross County
Scottish Football League Division One leaders Ross County maintained their three-point advantage with victory over Morton.
There were few chances in the first half as both sides cancelled each other out.
But the deadlock was broken 11 minutes before half-time when Stuart Kettlewell converted Colin McMenamin's cross.
Morton goalkeeper Colin Stewart made saves from long-range efforts by Iain Vigurs and Richard Brittain after the break.
But the keeper then had the misfortune of scoring an own goal to seal County's win after initially saving Kurtis Byrne's shot.
