Kumar Sangakkara’s 112 in the last innings in his home ground and four wickets from fast bowler Suranga Lakmal set up an emphatic 90-run win for Sri Lanka in the sixth one-day game against England and an unassailable lead in the series.

The Sri Lankans lead the seven-match series 4-2 with one match to be played.

The home side won the toss and rode Sangakkara’s run-a-ball century and a 153-run partnership between him and Tillakaratne Dilshan (68) to reach 7-292 in 50 overs.

England faltered in their chase early and never recovered to be dismissed for 202 in 41.3 overs.

Lakmal, on his return to international cricket after an injury layoff, took 4-30 while spinner Sachithra Senanayake returned 3-33.
