Leitrim are now second from the bottom in division three after suffering a 1-15 to 0-9 defeat at Carrick-on-Shannon writes Michael Cooke.
Leitrim left themselves with a mountain to climb in the second half-having trailed by 1-7 to 0-3 at half-time as Cork turned on the style just before the break.
The nine point defeat seemed unlikely after 14 minutes where Cork led three points to two with Keith Beirne scoring both for Leitrim.
Keith Beirne managed one more pointed free in the first-half as Cork dominated the remainder of it.
Ciaran Sheehan was very much to the fore, scoring 1-1 in the space of four minutes helping the Rebels to a seven-point lead at the break.
Tadhg Corkery stretched Cork’s lead to eight points in the 44th minute before a brace from Beirne reduced the deficit to six.
Cork later restored their eight-point cushion on the hour, Sean White slotting over a point.
Evan Sweeney and Keith Beirne then responded with one each for the home team before Luke Connolly hit four points on the trot to give Cork a ten-point buffer.
Ray Mulvey managed one more score for Leitrim the Rebels still had nine points to spare at the final whistle.
