Brighton boosted their hopes of European qualification with a thumping Premier League victory over struggling West Ham that increases the pressure on Hammers boss David Moyes.
Alexis Mac Allister put Albion in front midway through the first half, converting from the spot after Jarrod Bowen bundled Kaoru Mitoma over in the area.
Substitute Joel Veltman doubled the hosts' lead soon after half-time, chesting the ball in at the far post following a corner, before Mitoma slid in to make it 3-0.
Danny Welbeck added further gloss to the scoreline late on, drilling a right-footed shot into the bottom corner to condemn the Hammers to their biggest defeat of the season.
