Cenk Tosun and Idrissa Gueye scored in either half as Everton piled the pressure back on relegation battlers Huddersfield with a 2-0 win at The John Smith's Stadium.
Turkey forward Tosun's clinical finish gave Everton a half-time lead and Senegal midfielder Gueye blasted home their second with 13 minutes left.
It was a damaging defeat for Huddersfield, whose victory over Watford in their last match had given their survival hopes a big lift.
A seventh home loss of the season, though, coupled with wins for relegation rivals Crystal Palace, Southampton and West Brom, has left David Wagner's side three points above the drop zone.
Everton have now lost only one of their last seven games, winning four, but their travelling fans made clear their displeasure at the continued presence of Sam Allardyce in their dugout.
