Craig Bellamy's 85th-minute strike handed Cardiff a 1-0 victory at South Wales rivals Swansea and avenged their home defeat by the same scoreline earlier in the season.
Swansea had beaten the Bluebirds on their own turf back in November but Bellamy was on target to fire his hometown club to victory with a 25-yard strike.
The result lifted Dave Jones' men above their rivals and into third spot in the npower Championship table.
The first chance of the game fell to Jay Bothroyd, who missed the target from 12 yards inside the opening minute.
Moments later Swansea midfielder Darren Pratley fired goalwards from the edge of the penalty box. However, his effort was blocked by Dekel Keinan and Alan Tate then headed over a free-kick by Mark Gower.
Cardiff went close in the 11th minute when Aaron Ramsey hit a right-foot shot from 20 yards which was parried by Dorus De Vries as the visitors signalled their attacking threat.
Shortly before the half-hour mark, Scott Sinclair latched onto Gower's pass but, as he charged down on Tom Heaton's goal, Mark Hudson made a vital challenge to avert the danger.
Pratley also shot over before Bothroyd became the first player to be booked for a late challenge on Tate shortly before half-time.
Gower fired the Swans' first attempt of the second period wide of goal before Cardiff twice came close in quick succession. In the 59th minute, a cross from Peter Whittingham was headed wide by Paul Quinn and Darcy Blake then fired against a post from 12 yards with a left-foot shot.
And Bellamy sealed the contest when he collected a pass from Ramsey and fired a right-footed shot into the bottom corner from 25 yards to settle the match.
