Birmingham let a two-goal lead slip against Liverpool as they were denied a crucial win in their relegation battle.
Mikael Forssell lashed in a shot at the far post to put the Blues ahead, with Sebastian Larsson's exquisite long range free-kick adding to their lead.
But Peter Crouch guided in a shot to haul the Reds back into the game.
And as Liverpool penned the Blues back, Yossi Benayoun equalised with a deflected header, which all-but secures fourth spot for the Anfield side.
The point moves them nine ahead of fifth-placed Everton, who have three games left but an inferior goal difference.
Liverpool made nine changes to the team which drew 1-1 with Chelsea in the Champions League in midweek, although there was only one change from the second string side which beat Fulham last week.
There was little in the way of goalmouth action in the early stages but Birmingham slowly increased their level of urgency.
Rafael Benitez was heartened by Liverpool's fight
Olivier Kapo showed some good skill to get to the byline, only to power in a cross which everyone missed when he was better placed to pick out a team-mate.
James McFadden did not make the same mistake when he teased John Arne Riise to give himself space to cross for Forssell, who chested the ball down and fired in a shot.
Crouch's low, long-range effort forced Maik Taylor into a scrambling save but Birmingham held on to their lead going into the interval.
Liverpool tried to raise their game in the second half but their play lacked a cutting edge as they struggled to pierce the resolute defence of the home side.
The Reds lacked a player with the creative mould of ex-Everton striker and Birmingham playmaker McFadden and he had a hand in his side's second goal.
The Scot was brought down by Martin Skrtel and Larsson curled in the set-piece from 30-yards, with Radhi Jaidi stood in front of keeper Jose Reina, putting him off.
Crouch sidefooted the Reds back into the game after ex-Blues winger Jermaine Pennant's good work to set up a nervous finish at St Andrews.
Andriy Voronin and Benayoun each went close for the visitors with Liverpool forcing their opponent on to the backfoot.
Pennant was a key figure in Liverpool's comeback as he started exerting the same influence as McFadden.
And Birmingham finally buckled when Benayoun levelled with a header which went in after Jaidi's deflection.
•Birmingham boss Alex McLeish: "My feelings are a little bit mixed. I'm angry, particularly with the first goal we let in. There was a bit of naivety and it cost us dearly.
"Their second was a bit scrappy but they had the smell of blood.
"We didn't throw away two points but Liverpool earned it. But what I did get was a great reaction from the players after the loss to Aston Villa."
•Liverpool boss Rafael Benitez: "The team was controlling the game in the first half but we conceded a goal that changed things a bit.
"The second goal gave them more hope and we needed to score and did so.
"We scored the second goal with a bit of luck but we created enough chances to win. The players showed character and quality."
