Newcastle United suffered a second-half collapse as they were comprehensively beaten by Everton at Goodison Park on Thursday night.
Eddie Howe's side arrived on Merseyside on the back of impressive home wins against Chelsea and Manchester United but it proved to be one game too far for the injury-hit squad.
After perhaps being fortunate to be level at the break, goals from Dwight McNeil, Abdoulaye Doucoure and Beto earned the hosts a 3-0 win which takes them out of the relegation places, following their 10-point deduction.
Howe made just one change from the team that beat Manchester United as Martin Dubravka replaced Nick Pope in goal, with the number one choice expected to be out for some months with a shoulder injury.
The hosts started brightly but it was arguably Newcastle who carved out the first real opportunity, with Miguel Almiron firing straight at Jordan Pickford after being played in by Joelinton.
The Toffees were looking dangerous from crosses all night and Dominic Calvert-Lewin was guilty of missing two great chances, first with his head and then on his left foot, when he was found unmarked in the centre of the box just a few yards from goal.
Alexander Isak should have punished Everton's wastefulness in front of goal when he headed Kieran Trippier's cross wide, and the hosts would certainly not be as generous in the final third in the second half.
Trippier gifted McNeil possession in a dangerous area and the former Burnley winger drove forward before unleashing a powerful strike which flew past Dubravka into the top corner, making it 1-0 on 79 minutes.
Newcastle pushed for an equaliser but Dyche's side made the points safe when Trippier was again punished for a slack pass, as Jack Harrison crossed for Doucoure to finish inside the box.
There was still time for a third, as Portuguese striker Beto scored his first Premier League goal after running through on goal to finish low past Dubravka, delighting a jubilant Goodison Park.
Newcastle's depleted squad have just two days to rest before their trip to face Tottenham Hotspur on Sunday afternoon.
