Inverness Caledonian Thistle picked up their first win since returning to Scotland's top flight with a stunning 4-0 rout of Dundee United at Tannadice.
Kevin McCann, the right-back on loan from Hibernian, broke the deadlock with a terrific strike from distance 11 minutes before the break.
Adam Rooney coolly slotted home the second after 51 minutes before Russell Duncan added a spectacular third with an audacious half-volley three minutes later.
Rooney rounded off the scoring with a penalty after 82 minutes as United's Europa League exertions against AEK Athens appeared to have caught up with them.
The hosts kept faith with the same starting XI that lost 1-0 to AEK on Thursday with midfielder Danny Swanson again missing out with an Achilles injury, while former Caley defender Darren Dods had to be content with a place on the United bench.
Thistle boss Terry Butcher, without injured captain Richie Foran, made one change from the side that lost to Celtic last weekend with David Proctor stepping in to replace right-back Ross Tokely.
Thistle ran out worthy winners, although Prince Buaben was unfortunate not to add a consolation goal for United in the closing stages when his neat volley rebounded back off the post.
