"Rizwan, Haris, Irfan and Azam are being assessed," he said. "There is a significant improvement in their fitness. They're part of the squad because we hope they will be fit for the Ireland series."

Hasan, who like Jamal is currently playing county cricket for Warwickshire, had his selection attributed by the PCB more to his experience and ICC tournament pedigree rather than current form. Hasan did enjoy a stellar PSL this year with Karachi Kings, for whom he took 14 wickets at an economy of 8.26, but was still not selected for the New Zealand series.

His selection appears to be based around belief in his ability beyond just hard numbers, and an opportunity to assess him in Ireland and England before this 18-man squad is whittled down to 15 for the T20 World Cup.

Pakistan play three T20Is against Ireland starting May 10, before playing four games against England. The deadline to announce the squad for the T20 World Cup (May 25) is after they play the first T20I against England (May 22).
