He had Upul Tharanga caught behind for nine and then trapped Kusal Mendis lbw for nought. <p></p> <p></p>Dickwella, Sri Lanka's wicketkeeper-batsman, then got going with several valuable partnerships including a crucial 67-run fourth wicket stand with Mathews. <p></p> <p></p>Phehlukwayo bowled Dickwella when the left-hander dragged a delivery onto his stumps midway into the innings. <p></p> <p></p>Mathews hung on with an uncharacteristic sedate knock to reach his 36th ODI fifty and help his team post a total that seemingly keeps them in the hunt. <p></p> <p></p>Ngidi, Phehlukwayo and pace spearhead Kagiso Rabada kept getting wickets to rattle Sri Lanka's middle and lower order and also checked the flow of runs in the last few overs. <p></p> <p></p>The islanders managed just 28 runs from the final 30 deliveries.
