A sensational first-half performance helped Dundee United to a resounding Scottish Premiership victory in manager Jim Goodwin's absence against pointless Kilmarnock.
A stunning strike from the edge of the area from full-back Will Ferry had United cruising to a three-goal lead at the break, following a contested Zac Sapsford penalty and a nice header from Emmanuel Agyei to open the scoring.
Kilmarnock's inability to keep goals out at one end was compounded by further frustration in front of goal as visiting goalkeeper Jack Walton made fine first-half stops to keep out a Joe Hugill shot and Mark O'Hara header.
When substitute Jesse Randall smashed in a wonderful Ferry cross late on it was no more than the visitors deserved as they won at Rugby Park in the Premiership for the first time in a a decade and secured a first league victory of the season in style.
Home boss Neil McCann gave defenders Cathal McCarthy and Jonathan Meir their debuts, but the German only last a half while McCarthy's central defensive partner Robbie Deas went off injured shortly after Agyei headed in Mehde Merghem's cross to put United ahead.
McCarthy was penalised for the visitors' penalty by referee Nick Walsh for what appeared to be a tug on a United jersey, with Sapsford claiming his fourth goal in nine games before Ferry's wonder strike rounded off a terrific first 45 for the Tangerines.
The second half struggled to match the quality or drama of the first, with Hugill missing a big chance for the home side just after the break before team-mate Michael Schonning-Larsen drew another fine save from the excellent Walton.
Max Stryjek pulled off a couple of good saves to keep the score down but was powerless to keep out Randall's effort for the visitors' fourth.
