Ten-man Queen of the South came from behind to thrash Arbroath and move 14 points clear at the top of the Scottish Second Division.
Steven Doris edged the visitors ahead on 18 minutes, just before Queens' Mark Durnan saw red for violent conduct.
But Derek Lyle's tap-in and Nicky Clark's shot from 20 yards turned the match in the hosts' favour.
Strikes by Daniel Carmichael, Stephen McKenna and Clark added to the Doonhamers' tally.
