Pakistan U19 began their four-match one-day series against England U19 with a commanding 177-run win at Arundel on September 9.
Usman Khan scored 151 from 136 balls and captain Farhan Yousaf made 115 from 133 as Pakistan recovered from 41 for two to post 332 for nine.
Usman and Farhan added 268 for the third wicket, transforming the innings after the early wickets. Their partnership gave Pakistan the platform to attack the final overs and set England a demanding target.
The bowlers then ensured there was no way back for the hosts. Mohammad Sayyam led the attack with four wickets as England were kept well short of the target.
The victory gave Pakistan a 1-0 lead in the four-match series, with the second game scheduled for September 12 in Guildford.
