A carefully crafted century by young batsman Babar Azam helped Pakistan put a competitive 219 in 50 overs after top and middle order’s failure.
Babar’s ton and Shadab’s steady fifty rescued Pakistan from a total collapse after Pakistan lost all its wickets cheaply with three major wickets falling within the power play.
Pakistan have retained the squad that secured victory in Dubai tie for their second clash against Sri Lanka.
Earlier, the green shirts avenged the Test defeat by outclassing the touring team with an 83-run win in the first ODI on Friday. Babar Azam scored an impressive hundred while Shoaib Malik smashed a quickfire half century to help Pakistan thump Sri Lanka by 83 runs in the first ODI.
The remaining matches will be played in Abu Dhabi (October 18) and Sharjah (October 20 and 23).
The two teams will also play three T20 internationals, two in Abu Dhabi (October 26 and 27) while the last is scheduled for Lahore on October 29.
