Clare all but sealed a place in the Division 4 final with a comfortable win over London in Ruislip.
A strong start and finish to the first-half put the Banner in control, with Gary Brennan dominant in midfield and full-forward David Tubridy continuing his fine scoring form with seven points.
London captain Sean McVeigh and Lorcan Mulvey tried to inspire the hosts with a couple of superb long-range points, but Tubridy’s seventh point allowed McDermott to empty the bench.
Paul Coggins’ London will surely beat Kilkenny next weekend, while a win for Clare over the same opposition on April 8 will ensure promotion from the bottom tier.
