Pakistan should be blamed for the last test loss. Their batting was been an issue which needs to be worked on. The only good thing that happened with Pakistan in this series is that they found a good player Aamer Jamal. Mohmmad Hafiz wanted to beat Australia in Australia, end up getting defeated 3 - 0. A total failure of Pakistan batting can be blamed for the whitewash.
For the very first time in this series Pakistan batting clicked in first innings of last test and there bowlers did a good job to restrict Aussies to 299. Now in second innings Pakistan should have scored 250 if they can't make another 300. The whole batting line up collapsed on just 115 runs. Pakistan should take some serious actions against its so called best bowlers who either abstained from participating in this series or got unfit in the series.
