Livermore forced the ball over the line in the 91st minute with relegation certain had they lost or drawn at The Hawthorns.
Jake Livermore’s last-gasp goal gave West Brom a victory against Tottenham which ensures they still have a chance of avoiding Premier League relegation.
However, the Baggies will still go down if Southampton wins at Everton in Saturday’s 17:30 BST kick-off.
Harry Kane went closest for the visitors in the first half and almost scored an own goal after the break.
In the first half of few clear-cut chances, Kane had the best of Spurs’ opportunities and his header from Erik Lamela’s cross was saved by Ben Foster.
West Brom’s Jay Rodriguez went close as half-time approached, sneaking in behind Victor Wanyama only for his header to be cleared off the line.
Kane almost became the Baggies’ hero when a mis-hit clearance almost flew into the back of his own net with Hugo Lloris acrobatically keeping it out.
But The Hawthorns exploded when Livermore found the back of the net after a scramble from a corner.
