Kusal Perera sent Pakistan on the run with his most substantial innings to date, then Sri Lanka's middle order ran the opposition down and mauled them in a frenzied finish, to found a 165-run victory in the final ODI.
Sri Lanka plundered 368 for 4, but even on a placid Hambantota deck, the chase was too steep for Pakistan's in-form top order. They slipped to 140 for 5 before the halfway stage of the innings, and were all out for 203.
Several Pakistani batsmen made starts which they failed to capitalize. Sachithra Senanayake took 3 for 39.
