GOALS from deadly duo Emmanuel Adebayor and Jermain Defoe inflicted a harsh defeat on Albion.
The Baggies deservedly opened the scoring in the tenth minute thanks to Youssouf Mulumbu's first goal of the season.
But for the third successive home game, another tale of penalty woe gave the visitors a helping hand, with Nicky Shorey this time conceding a debatable spot-kick for an alleged tug on Aaron Lennon.
Adebayor's penalty was saved by Ben Foster but the Togo international slotted home the rebound to level the scores on 25.
Albion did more than enough to earn a point from a pulsating Hawthorns encounter and they were unfortunate to have three credible penalty appeals turned down by referee Lee Probert.
But Defoe punished the hosts for missing gilt-edged chances with a crisp 81st-minute finish - and Adebayor added a third in stoppage time to put an unfair Spurs gloss on the final scoreline.
Shane Long won his fitness race with a leg injury to enable Roy Hodgson to name an unchanged starting XI for the first time in ten Barclays Premier League games.
And Albion were buoyed by the return from injury of Peter Odemwingie, Paul Scharner and Graham Dorrans, who were all handed bench berths.
Spurs were minus key men Luka Modric and Rafael van der Vaart as they called on Sandro and Defoe in their places.
The Baggies harried the visitors into several misplaced passes early on.
And Mulumbu continued to take the game to Spurs when he powered forward in the fourth minute before delivering a slide-rule pass that was just inches away from Long in the box.
Two minutes later, Tottenham produced their first threat when Sandro let fly with a low 25-yard strike that Foster spilt and was fortunate to see go wide for a corner.
But it was the Baggies who struck first in the tenth minute as Zoltan Gera's desire saw him beat Benoit Assou-Ekotto to the ball on the right.
The Hungary international played the ball back to Steven Reid, who delivered an inch-perfect cross for Mulumbu to head home to Brad Friedel's right from ten yards.
Albion were dealt a hammer blow in the 21st minute when Gera limped off after collapsing to the floor in a heap and was replaced by Simon Cox.
To make matters worse, Albion conceded a penalty for the third successive home game when Adebayor's flick played Lennon into the box.
Referee Probert adjudged Shorey to have pulled back the England winger, who went crashing to the floor.
Foster did well to dive low to his right to stop Adebayor's spot-kick, but the ex-Arsenal man fired home the rebound to equalise on 25.
Ledley King got above Gareth McAuley from Gareth Bale's free-kick in the 32nd minute and sent his header wide of the left-hand post.
The Baggies were appealing for a penalty of their own on 35 as Thomas went down in the box under Kyle Walker's challenge from Cox's pass.
A swift break then saw Defoe stopped by McAuley on the edge of the box and the ball dropped for Adebayor, whose curling effort was easily held by Foster.
Another moment of contention arose in the 39th minute when Reid's cross deflected up into the air off Assou-Ekotto and Friedel appeared to carry the ball over the goalline under pressure from McAuley.
But the assistant referee flagged for a foul by the Albion centre-half on the USA stopper.
Hodgson's men were calling for a spot-kick again on 40 when Long was challenged from behind by King from Cox's pass - but again to no avail.
Three minutes later, James Morrison tried his luck with a dipping volley from 35 yards that Friedel dealt with safely.
And a minute before the break, Mulumbu showed great determination to burst past Sandro into the box before forcing Friedel to save with his feet with a 15-yard drive.
Tottenham shifted the ball swiftly from end to end in first-half stoppage time and the Baggies were somewhat fortunate to see Defoe's 20-yard strike deflect wide off Jonas Olsson.
From the resultant Bale corner, Foster clutched Adebayor's header under his crossbar to keep the scores level at the break.
Morrison gifted possession to Scott Parker six minutes into the second half and the former West Ham man teed up Adebayor, whose fiercely-struck 15-yard shot was well palmed away by Foster high to his left.
Cox was presented with a glorious chance to restore Albion's lead in the 54th minute - but he headed straight at Friedel after Morrison had out-paced Assou-Ekotto on the right to get to the byline and centre.
Two minutes later, Defoe went through the gears to get past Olsson and Foster but from the tightest of angles, all he could do was direct the ball goalwards and Reid was able to clear the danger.
McAuley needed to be at his very best on the hour-mark as he timed his challenge perfectly to deny Lennon a clear sight of goal.
From the resultant Bale corner, King climbed highest and again headed wide of the far post from ten yards.
Defoe did well on 63 to deliver a cross from the right byline and Olsson had to be alert to clear ahead of Adebayor.
Long chased down what looked like a lost cause in the 65th minute and fired in a low cross that Younes Kaboul almost sliced into his own net under pressure from Cox.
Seconds later, Kaboul was lucky not to concede a penalty when he seemingly tugged Morrison back.
Play quickly changed ends and when Defoe flicked Bale's cross on, Adebayor looked set to score - but Foster was brave and stood his ground to clear the danger.
Hodgson made a change in the 72nd minute as Odemwingie returned from a knee injury to replace the tiring Long.
The Nigeria international almost made an immediate impact as he got in between King and Kaboul from Cox's near-post cross, but he could not get enough on the ball to direct it on target.
Defoe was proving a real handful and the England hitman slid in Adebayor, whose shot was saved by Foster.
Morrison then produced the run of the match as he skipped past three Spurs players before teeing up Brunt, who should have put the Baggies 2-1 up, but sent his right-foot volley over from 12 yards.
The hosts were undone by a sucker punch on 81 as Defoe raced onto Adebayor's clever touch and had Olsson back-pedalling before delivering a crisp 20-yard finish into the bottom left-hand corner of the net.
McAuley made a vital block six minutes from time to prevent Defoe making it three for the visitors.
Injury time saw Olsson's audacious overhead kick blocked and Tottenham sprinted up the other end, with Bale firing inches past the left-hand post from 12 yards.
Odemwingie then sent a good chance wide as he was first to Shorey's left-wing cross with his head.
A fortunate ricochet saw the ball fall to Bale at the death and he kept his nerve to tee up Adebaylor to add a third for Spurs.
