Pakistan have added Shahzaib Hasan and Wahab Riaz to their one-day and Twenty20 squads for the upcoming series against South Africa.
Both players have been rewarded with call-ups after producing excellent performances in Pakistan's domestic Twenty20 competition.
Opening batsman Shahzaib, 20, was the top scorer with 281 runs from four matches for Karachi, including hitting a century and two half-centuries.
Riaz, a left-arm seamer, claimed 10 wickets to help the Lahore Lions claim the Faysal Bank t20 title.
The 25-year-old had already been included in the Test squad having claimed a five-wicket haul on his debut against England at the Oval earlier this year.
Pakistan play two Twenty20 fixtures in as many days against the Proteas in Abu Dhabi before the nations then go head-to-head in a five-match one-day series that sees games played in both Abu Dhabi and Dubai.
Meanwhile, the Pakistan Cricket Board have introduced a new code of conduct promoting better standards of behaviour from their players.
Pakistan's recent tour of England was marred by allegations of corruption, and the International Cricket Council last week gave the PCB 30 days to install measures to "protect the integrity of the game and restore confidence".
"The new code of conduct is the first step towards fulfilling the ICC's recommendations," team manager Intikhab Alam said.
"There is a lot more stress on creating awareness among players about anti-corruption laws and regulations. We hope the new code will help us in dealing with the disciplinary and corruption problems."
Intikhab briefed the Pakistan players about the new code at a training camp in Lahore ahead of the games against South Africa.
Pakistan squad: Imran Farhat, Mohammad Hafeez, Mohammad Yousuf, Misbah-ul-Haq, Umar Akmal, Asad Shafiq, Fawad Alam, Shahid Afridi, Abdul Razzaq, Umar Gul, Saeed Ajmal, Abdur Rehman, Shoaib Akhtar, Tanveer Ahmed, Zulqarnain Haider, Shahzaib Hasan, Wahab Riaz.
