In the Australia vs Pakistan ICC Women's World T20 at Providence, Nov 9 2018 match, unless I got it wrong, looks like Pakistan has used an all spin attack, Anam Amin (sla), Sana Mir (ob), Nida Dar (ob), Nashra Sandhu (sla) and Aliya Riaz (ob). I wonder if this has happened any time before in an international match.
