Opener Asif Ali played a lone hand of 39 as stalwarts like Brad Haddin (nought), Misbah-ul-Haq (13) and Shane Watson (eight) all failed. Karachi's batsmen had also struggled after left-arm paceman Rumman Raees returned figures of 4-25 in his four overs. Babar Azam and Shoaib Malik top-scored with 25 each in the play-off clash.
Karachi will now meet Peshawar Zalmi in the last play-off on Friday in Dubai with the winner to take on Quetta Gladiators in Sunday's final in Lahore. The Pakistan Cricket Board (PCB) on Monday decided to still stage the final in the city despite last week's two bomb blasts which killed 22 people and left over 100 injured.
However, five Quetta players - Kevin Pietersen, Luke Wright, Rilee Rossouw, Tymal Mills and Nathan McCullum - have refused to go to Pakistan over security fears. The PCB insist they will be replaced by some other foreign players.
Lahore has been the scene of violence affecting cricketers before. In 2009, Sri Lanka's team bus was attacked by gunmen who killed six policemen. Several of the Sri Lanka team and staff were injured and the bloodshed turned Pakistan into a 'no-go zone' as far as international teams were involved. "It's with a heavy heart I will not be coming to Lahore. I have a young family and for me a game of cricket is just not worth the risk," tweeted 31-year-old Wright.
