Eoin Doyle got the rout underway in the fifth minute, getting on the end of Joseph Ndo's delightful chip over the top to muscle past Stephen Walsh and blast home from inside the box.

Paul Cook's side doubled their lead in the 16th minute after a sustained period of pressure, Richie Ryan's bullet of a shot from the edge of the box having too much power for Conor Winn in the United goal.

Walsh was poor for Sligo's first goal and was at fault again when the league leaders extended their lead in the 34th minute. He delayed on the ball ten yards inside his own half and then slipped as Matthew Blinkhorn closed in.

The striker nicked possession and found Raf Cretaro outside and he skipped past Paul Sinnott to fire past a helpless Winn.

The night became more difficult for the home side in the 36th minute when they were reduced to ten men, Eduardo Dusi picking up a second yellow card ten minutes after his first.

Sligo didn't take long to make their numerical advantage count, Blinkhorn smashing home their fourth from the right corner of the box in the 39th minute. He added his second of the night - and his side's fifth - a minute from the break following good work from Ryan and Alan Keane.

Blinkhorn claimed the match ball in the 74th minute, Keane once again picking out the striker who fired past Winn for his hat-trick.

The visitors were in seventh heaven two minutes later when John Dillon, not long on as a sub, let fly from 15 yards, and his effort took a wicked deflection off Paul Sinnott to wrongfoot Winn, the goal going down as an own goal.

The rout was completed four minutes from time, Keane going on another lung-bursting run down the right before picking out Doyle, who beat Winn at the second attempt.
