Norwich City became the first team to be relegated from the English Premier League after Michail Antonio four-goal blitz handed struggling West Ham a much-needed boost in their own survival battle.
The Canaries suffered a seventh successive league to leave them marooned at the foot of the table, 13 points from safety with only three games – and a maximum nine points – available.
Daniel Farke’s side have struggled with the step up to the topflight after winning the Championship last season and relegation is Norwich’s third in seven seasons.
Antonio’s superb performance in front of goal sealed a first away win for David Moyes’ team who are now six points above the relegation zone, with two of their remaining three matches at home to fellow strugglers Watford and Aston Villa.
The forward’s first came from inside the area from Issa Diop’s flick from a corner in the 11th-minute before using his head to guide Mark Noble’s free-kick beyond Tim Krul on the stroke of halftime.
Antonio completed his hat-trick from a rebound after Tim Kruul had saved from Hammers captain Mark Noble. His fourth came from a tap-in from a Ryan Fredericks pass.
Relegation always looked inevitable for the Canaries who suffered a 24th league defeat and failed to score for a league-high 17th game this season.
Elsewhere, Troy Deeney scored two second-half penalties as Watford came back from a goal down to beat Newcastle and move six points clear of the bottom three.
Dwight Gayle put the Magpies ahead in the first half but Deeney put Watford level with his first penalty after Kiko Femenia was fouled by Ritchie.
The Watford captain then blasted the Hornets to victory with his second spot-kick eight minutes from time after a Javi Manquillo foul on Ismaila Sarr.
