Earlier, of the two pacemen, who opened England's attack, Steven Finn (1/23) was very effective as he swung the ball impressively and had Tillakaratne Dilshan (16) trapped early.
The strip offered bounce to the pacers and Finn, who has bowled the most dot balls in the tournament, did trouble the Sri Lankan openers.
Dilshan and Jayawardene though adjusted well, hitting a six each off Jade Dernbach in the fourth over. He though, was unlucky as Swann had dropped Dilshan in his very first over.
