England won the second test against Sri Lanka in some style when man of the match Kevin Pietersen smashed Tillakaratne Dilshan for six over mid wicket to complete an eight-wicket victory on the fifth and final day on Saturday.
Pietersen followed his momentum-swinging first innings knock of 151 with an unbeaten 42 off 28 balls.
That included two sixes and four fours as England raced to their target of 94 inside 20 overs.
England's victory charge was triggered by off-spinner Graeme Swann, who claimed his second 10-wicket haul to bowl Sri Lanka out for 278 in their second innings.
England lost their captain Andrew Strauss for a duck in the first over and Jonathan Trott for five in the run chase that ensued.
Cook and Pietersen forged an unbeaten 66 runs stand for the third wicket to see them home and draw the two match series 1-1.
Scores: Sri Lanka 275 (M Jayawardene 105, T Samaraweera 54, A Mathews 57; G Swann 4-75, J Anderson 3-62) and 278 (M Jayawardene 64, Swann 6-106) v England 460 (A Strauss 61, A Cook 94, J Trott 64, K Pietersen 151; R Herath 6-133).
