Craig Dawson scored at both ends as West Brom held Tottenham to a 1-1 draw and put a huge dent in their Premier League title bid.
Spurs went into the game at White Hart Lane needing to pick up three points to move back to within five points of league leaders Leicester with just three matches remaining.
And the north Londoners dominated the first half but only had DawsonÂ’s scrappy own goal to show for their efforts.
Albion improved after the interval and capitalised on TottenhamÂ’s nerves at only holding a one-goal lead as Dawson levelled inside the final 20 minutes.
Spurs tried to rally again to grab an all-important winner but failed to break down the BaggiesÂ’ back-line.
The point leaves them seven adrift of Leicester, who can secure the title with a win at Manchester United this weekend, while West Brom are up to 13th on 41 points.
Spurs started strongly with Christian Eriksen seeing a free kick from 25 yards tipped past the post by Boaz Myhill in the fifth minute.
Three minutes later some excellent passing play resulted in Dele Alli playing in Harry Kane down the right of the area but Myhill somehow managed to push his effort on to the inside of the far post.
On 13 minutes Stephane Sessegnon brought down Danny Rose on the edge of the area and Eriksen curled his right-foot free-kick towards the far corner from the left but watched as it clipped the top of the crossbar.
Myhill was again called into action in the 20th minute when Claudio YacobÂ’s slip gave Kane the yard he needed to get a shot off from just outside the area, but the Baggies’ custodian was equal to the task and he parried the effort wide of his near post.
West BromÂ’s first and only chance of the half came on the half-hour but Craig Gardner put the ball over the bar in the middle of the area after good work from Dawson down the right.
Spurs finally took the lead in 33rd minute when Eriksen swung a dangerous free kick into the area and Dawson only managed to divert the ball through MyhillÂ’s legs when trying to stop Jan Vertonghen from getting on the end of it.
West Brom had a bright spell at the start of the second half without really troubling the Spurs defence, before the hosts hit the woodwork for a third time in the game on 58 minutes.
Eriksen burst away down the left and crossed into the middle for Erik Lamela who managed to hit a first-time, side-foot effort which rolled against the far post with Myhill beaten.
West Brom went close to equalising on 63 minutes when GardnerÂ’s ball in from the left was met by the head of Salomon Rondon whose effort was inches past the front post.
Spurs responded to that scare instantaneously with Eriksen racing through the middle before digging a right-foot shot out which bounced inches wide.
West Brom started growing into the game with Spurs unable to grab the all-important second goal and Rondon went close again when the hosts failed to clear their lines and he lashed an angled strike from the right of the area which Hugo Lloris tipped over.
From the resulting left-wing corner on 73 minutes Dawson got above Eric Dier and beat Lloris to the ball to head into the empty net and make amends for his earlier own goal.
To add insult to injury Dier picked up an injury when being caught by Lloris and had to go off.
Spurs pushed for the remainder of the game and through five minutes of stoppage time but could not find the elusive winning goal.
