Hasan Ali (3/43) was another Pakistani paceman who made an impact at the start of the innings.
Two balls later, medium-pacer Fahim Ashraf struck on his ODI debut when Dinesh Chandimal played on for a duck.
All-rounder Mathews, fresh from an unbeaten fifty in Sri Lanka's shock seven-wicket victory over India, drove off-spinner Mohammad Hafeez for six, while Dickwella ended a sequence of 54 balls without a boundary by cover-driving left-arm spinner Imad Wasim for four.
