Brighton remain unbeaten in the Premier League at the London Stadium, though their current winless streak has extended to five matches.
Mohammed Kudus rescued a point for West Ham as they played out a 1-1 draw with Brighton on Saturday.
The Hammers remain without a win from their eight Premier League meetings with the Seagulls at the London Stadium, and could have been dealt another defeat late on.
Mats Wieffer volleyed home his first Brighton goal to put Fabian Hurzeler’s side ahead in the 51st minute, though Kudus restored parity just before the hour mark.
But West Ham goalkeeper Lukasz Fabianski preserved a point for his side in second-half stoppage time, producing a brilliant save from close range to deny substitute Yasin Ayari.
There is no change in the table for either side. West Ham remain 14th on 20 points – five fewer than Brighton, who stay ninth after missing the chance to move as high as sixth.
Data Debrief: Seagulls succeed where Farah and Bolt don't
Brighton, who could not hold onto their lead, have now failed to win any of their last 11 Premier League games in London.
Nevertheless, unlike Mo Farah and Usain Bolt, the Seagulls have never been beaten at the London Stadium since its existence.
Meanwhile, for the first time this season, West Ham have picked up a point after conceding the first goal in a home Premier League match.
