A goal from Danny Welbeck was enough to punish Newcastle for a series of missed opportunities and launch Brighton into the top five, before the striker had to be stretchered off with a worrying back injury.
The home team started strongly, Anthony Gordon giving Lewis Dunk nightmares by cutting in from the left, and Alexander Isak wasted a brilliant early chance and Bart Verbruggen saved another superbly.
In stark contrast, the Seagulls needed just one chance to make Newcastle pay. Danny Welbeck played a strong one-two with Georginio Rutter to score his fifth goal of the campaign, equaling his tally from last season.
The Magpies continued to press in the second half and this time it was Gordon’s turn to squander a chance, nodding home from Isak’s cross.
But Brighton continued to frustrate Newcastle with a determined defensive display, and Verbruggen showed why Bayern Munich reportedly want him to be Manuel Neuer’s heir.
