Actually they will.
All they have to do is beat UAE comprehensively to increase their run rate and just beat Ireland. If they loose from South Africa, they will still qualify.
BUT I have a feeling, they will give South Africa a hard time or even beat them after winning 3 in a row. They must play the leggie and 3 fast bowlers.
If they end up doing that, then they need to take one match at a time and who knows they may end up being in the Semis or even the Finals.
Being too optimistic...Why not, after all Pak is the most unpredictable team to play the cricket.
FINGERS CROSSED!!
