London - Sri Lanka, after losing the toss, made 300 for nine against England in the fourth one-day international at Lord's on Saturday.
Kumar Sangakkara's 112, his first century at Lord's in any format, was the cornerstone of Sri Lanka's total.
Together with Tillakaratne Dilshan (71), he put on 172 for the second wicket after Sri Lanka had collapsed to 67 all out during a 10-wicket defeat in the third ODI at Old Trafford on Wednesday.
England lead the five-match series 2-1.
