Ashley Vincent's tidy finish put the home side ahead on four minutes, Andy Lindegaard almost doubling the lead before half time.

Jason Scotland brought Swansea level five minutes into the second with a composed finished.

Swansea's second-half dominance finally paid off when Robinson cut inside and fired a drive into the bottom corner.

The visitors continued to create chances in the final 20 minutes, but they needed a fine save from goalkeeper Dorus de Vries to deny former Swans striker Paul Connor.

Swansea's win came at a cost, though, as Robinson and Leon Britton picked up hamstring injuries.
