Ireland captain William Porterfield has won the toss and opted to bat in his side’s crunch clash with Pakistan at Adelaide Oval.

The match is essentially a World Cup octo-final, with the winner to face Australia in Friday’s quarter-final at the same venue.

Towering Pakistan paceman Mohammad Irfan has been sidelined by a hip injury, while Younis Khan is also out of the final pool fixture of the tournament.

Haris Sohail and Ehsan Adil were added to Pakistan’s XI in place of Irfan and Khan.

Ireland opted against making any changes to the side that suffered an eight-wicket loss to India last Tuesday.

Pakistan: Sarfraz Ahmed, Ahmed Shehzad, Haris Sohail, Misbah-ul-Haq (capt), Sohaib Maqsood, Umar Akmal, Shahid Afridi, Wahab Riaz, Sohail Khan, Rahat Ali, Ehsan Adil

Ireland: William Porterfield (capt), Paul Stirling, Ed Joyce, Niall O’Brien, Andy Balbirnie, Kevin O’Brien, Gary Wilson, Stuart Thompson, John Mooney, George Dockrell, Alex Cusack.
