Federico Bessone smashed home a late winner as Swansea moved up to third in the Coca-Cola Championship with a richly deserved 1-0 victory over struggling Derby.
Paulo Sousa`s side, who went into the game on the back of a 10-match unbeaten run, were in control throughout at the Liberty Stadium but were unable to apply the necessary finishing touch until Bessone`s 81st-minute winner - his first goal for the club.
The Argentinian latched onto a delightful through ball from substitute Joe Allen before thumping home a left-footed shot into the top corner to the delight of the home faithful.
Although Derby defended bravely, they could have few complaints with the final result having failed to offer anything by way of an attacking threat.
And while Swansea look set to challenge at the top end of the table this season, the Rams remain in 18th - just three points clear of the relegation zone.
