Substitute Carlos Vela rescued a point for West Brom with an injury-time equaliser as the Black Country derby with Wolves at The Hawthorns finished in a 1-1 draw.
On-loan Tottenham midfielder Jamie O'Hara's stunning strike looked to be sending Roy Hodgson to a defeat in his first game as Baggies boss.
But, with seconds remaining, Wolves keeper Wayne Hennessey spilled James Morrison's shot and Vela, who is on loan from Arsenal, converted the rebound.
Hennessey was called upon to make the first save of the game after 21 minutes but he easily dealt with Jonas Olsson's header from Chris Brunt's corner.
Marc-Antoine Fortune should have done better when he headed over the bar from close range.
Then five minutes before half-time a stunning strike from O'Hara put Wolves ahead. Kevin Doyle won a free-kick when he was brought down by Gabriel Tamas 25 yards from goal. Albion were caught napping when Nenad Milijas squared the free-kick to O'Hara and his curling shot flew into the roof of the net.
Wolves had the chance to double their lead with a 4-2 numerical advantage on the counter-attack. But Doyle hesitated, when O'Hara was free to his left, and was crowded out.
Matt Jarvis wasted a golden opportunity to get wolves a second after 51 minutes. Tamas made a mess of trying to head the ball back to Hennessey and Jarvis nipped in with only the keeper to beat. But, from 10 yards, out he dragged the shot wide.
But Jarvis atoned for his earlier miss when he headed a near post Olsson header off the line.
With seconds remaining, Vela equalised for Albion after Hennessey spilled James Morrison's low drive.
