Substitute Haydon Roberts fired a last-gasp winner as Bristol City strengthened their Sky Bet Championship play-off bid with a 2-1 win over a West Brom side who finished the game with 10 men.
The home side went in front after 56 minutes when Nahki Wells turned his marker on the edge of the box and arrowed a low right-footed shot into the bottom corner.
But Albion were level six minutes later when Alex Mowatt capitalised on a collision between advancing goalkeeper Max O’Leary and defender Cam Pring to shoot unchallenged into an unguarded net.
The Baggies had Jayson Molumby sent off for clattering into City substitute Joe Williams after 89 minutes and conceded in the last of five minutes of stoppage time when Roberts’ low shot from 10 yards squeezed between the legs of Albion goalkeeper Josh Griffiths.
The goal put the Robins fifth in the table and opened up a six-point gap on eighth-placed Albion, who now have it all to do to make the top six.
Much of the first half failed to live up to a vibrant atmosphere. But it took two fine saves from Griffiths to keep Albion on level terms, the first diving to his right to keep out a powerful left-footed drive from Wells in the 36th minute.
Griffiths did even better seven minutes later, going down smartly on his goal-line to smother Ross McCrorie’s close-range shot after Wells had produced a clever turn and cross to set up the chance.
O’Leary was only called upon to catch a 27th-minute header from Kyle Bartley directed straight at him. But there was a heart-stopping moment for the City keeper after 35 minutes when his attempt to pass out of his own area saw the ball strike Albion’s Isaac Price and bounce back into his arms.
Bristol City shaded the first half and created another good chance after 52 minutes when Wells ran onto a George Earthy pass and forced another save from Griffiths.
At the other end, O’Leary had to dive on his line to deny Adam Armstrong. Seconds later Earthy shot wide before Wells’ brilliant strike sent home fans into ecstasy.
It was West Brom fans cheering when a lack of communication between O’Leary and Pring led to Mowatt’s equaliser.
With his side back in the game, Baggies boss Tony Mowbray then made four substitutions in the 65th minute, sending on Daryl Dike, Ousmane Diakite, Tom Fellows and Tammer Bany Odeh.
Albion were on top for the first time and O’Leary had to dive to keep out a Diakite header. City head coach Liam Manning responded with four subs of his own after 75 minutes as Williams, Roberts, Yu Hirakawa and Sinclair Armstrong entered the action.
A frantic finale saw O’Leary save again from Diakite before Molumby’s red card and Roberts’ dramatic late clincher had Ashton Gate rocking.
