Experienced left-arm pace duo of Muhammad Amir and Wahab Riaz were included in Pakistan's final 15-member World Cup squad following their 0-4 loss to England in the ODI series.
Both the bowlers were not included in the initial World Cup squad announced last month but Aamir, who is yet to recover from chickenpox, was named for the one-day series against England which Pakistan completed on Sunday.
The selectors have axed allrounder Faheem Ashraf and left-arm pacer Junaid Khan from their initial World Cup squad to make way for the two senior players.
The selectors had discarded Wahab from the tour to England but after the thrashing given to the Pakistani pacers in the one-day series they apparently had a change of mind.
Wahab, who turns 34 next month, last played a one-day international for his country in the opening match of the 2017 Champions Trophy against India going for 87 runs without a wicket and than limping off with a injury.
Since then the selectors have ignored him for 50-overs cricket while Aamir also didn't feature in the series against England after contracting chickenpox and his form remains a concern after he took just five wickets in his last 14 ODIs since the Champions Trophy.
According to the cricket board, Amir has recovered from his chickenpox and he and Wahab will be available for the warm-up matches against Afghanistan and Bangladesh this week.
In another major decision, the selectors have dropped young batsman Abid Ali from their World Cup squad to make way for the hard-hitting Asif Ali.
Ali was initially not part of the World Cup squad and went to England for the ODI series where he scored two half centuries.
"The lack of potency of our frontline bowlers in the recent ODI series meant that a change was needed. In addition, we now know that we will encounter batting wickets throughout the World Cup campaign," Chief Selector, Inzamam-ul-Haq said.
"The combination of these elements, meant that we believed right now, utilising the World Cup experience and knowledge of Wahab was the correct choice," he said.
"Wahab has been training and playing club cricket, and the player of his calibre will not face much problem in adapting and adjusting to the gruelling demands of the World Cup," Inzamam said.
On the exclusion of Abid Ali, Inzamam said: "It was not an easy decision to leave him out particularly after he got only one opportunity on the tour. But, he was our third choice opener. After both struck early form, we preferred Asif Ali as he brings firepower to the team that can strengthen our chances in the tournament," the Chief Selector said.
Abid, despite being a member of the initial World Cup squad, was given just one opportunity on the entire tour.
Inzamam said the final 15-member squad was announced in consultation with the captain and head coach.
Wahab has been included in the squad in place of allrounder, Faheem Ashraf while the experienced left arm pacer, Junaid Khan has also been dropped after playing in just two ODI matches against England.
Pakistan World Cup squad: Fakhar Zaman, Imam-ul-Haq, Babar Azam, Haris Sohail, Asif Ali, Shoaib Malik, Muhammad Hafeez, Sarfaraz Ahmed (Capt), Imad Wasim, Shadab Khan, Wahab Riaz, Muhammad Amir, Hasan Ali, Shaheen Shah Afridi and Muhammad Hasnain.
Poor fielding worries Arthur
After conceding a 0-4 series defeat against England, Pakistan head coach Mickey Arthur admitted that his side did not perform well in the bowling and fielding departments which led to their loss in the five-match rubber.
On Sunday, hosts England comfortably defeated Pakistan by 54 runs in the final ODI of the series and made sure that their World Cup preparations were on track and they remain the hot favourites for the showpiece event.
Pakistan, who are usually termed as a very good bowling side, lacked bite and conceded totals in excess of 300 in the four completed matches. And towards the end of the series, their poor fielding, which saw regulation catches being put down and a slew of misfields, also raised questions over their World Cup chances with less than two weeks to go.
"Our fielding has been very disappointing. That has been a massive difference between the two sides," ESPNcricinfo quoted Arthur as saying after the loss at Leeds.
"At Southampton and Nottingham, it was anybody's game going into the last five overs. We competed really well. The one difference has been our fielding and that's a real worry for me," he added.
The Pakistan head coach was, however, happy with the way the batters performed against the number one ranked ODI side.
"We sit here and take a hell lot of the positives out of this series. Our batting has gone to another level and we have batted extremely well. That's given our dressing room a massive amount of confidence. When we were coming to England, people were saying we were a 280 team. I am taking a fair amount of positives certainly in that department out of this series," said the South African.
"Our bowling and fielding has been average at best. Another thing is that we played against a team which is number one in their own conditions. I don't think there are too many other teams around in England as prepared as we are in terms of the competition we played against and match fitness, which is something very important," he added.
Despite the humiliating series loss, the 51-year-old insisted that he was confident that his side will perform well in the World Cup.
"We've got a couple of days now to regroup, two warm-up games and then we'll go. I'm very, very confident with the players we've got. We need to sharpen up on a couple of disciplines but we'll certainly get there. We'll be good," he said.
