A chanceless unbeaten 134 from Kumar Sangakkara inspired the Sri Lankan cricketers to a seven-wicket win over England at the Oval to leave Champions Trophy Group A wide open ahead of the final two matches.
A victory in the clash would have taken England through to the semi-finals as one of the top two and defeat would have dumped Sri Lanka out but all is now left to play for with New Zealand leading the group on three points.
England, who next face New Zealand in Cardiff on Sunday, and Sri Lanka are on two points with Australia on one ahead of their meeting with Angelo Mathews' side at the Oval on Monday.
England made 293 for seven with Sri Lanka reaching their target with almost three overs to spare.
