Sangakkara, who posted unbeaten centuries in wins over Bangladesh and England before being out for 104 in last Sunday's loss to Australia, was caught behind for 124 off 95 balls, including 13 boundaries and four sixes.
Sri Lanka was in complete control until Josh Davey (3-63) took the first of his key wickets to dismiss Dilshan to make the total 216-2. He removed Mahela Jayawardene (2) and Sangakkara on consecutive balls in the 37th over as Sri Lanka wobbled to 244-4. Davey is the leading wicket-taker in the tournament with 14.
