Hasan Ali and Rumman Raees spearheaded the Pakistani assault with their impressive performances, taking 3-36 and 3-49 respectively to restrict Sri Lanka to 209 in 50 overs.

The victory was a good response by Pakistan after losing the preceding two-match Test series 2-0, in their first ODI since winning the Champions Trophy in England four months ago.

Lahiru Thirimanne was the only Sri Lankan top-order batsman who played with any authority for his 53 as Pakistan took regular wickets to take a 1-0 lead in the five-match series.

Akila Dananjaya (50 not out) and Jeffrey Vandersay (25) delayed the result as they took Sri Lanka from 132-7 to 200-8 during their 68-run eighth-wicket stand but it was too little, too late.

Earlier, Pakistan scored 292 for six in their 50 overs, led by a brilliant 103 by Babar Azam and helped by a quick-fire 81 off 61 by Shoaib Malik.

Azam faced 131 deliveries for his sixth ODI hundred, as the pair added 139 for the fourth wicket after Sri Lanka had won the toss and opted to bowl first.

Malik joined Azam at 124-3 and smashed five fours and two towering sixes before holing out at deep midwicket off the last ball of the 47th over.
