You are probably right. Pakistan elected to bat after winning the toss. I thought maybe Pakistan's top order would bat responsibly today. But even in today's match Pakistan batsmen could not start well. Pakistan team lost 2 wickets for 38 runs and third wicket for 86 runs. Pakistan team is not playing well. Babar Azam and Iftikhar are batting now. At the end of 20 overs, Pakistan collected 102 runs with the loss of 3 wickets. Pakistan's run rate is good enough but their top order is not playing well. 300 will be much more difficult for Pakistan now. I don't think it is possible for South Africa team to win if they target below 300. Because South African batsmen are in very good form now. They have batted well in every match. Pakistan is likely to lose in today's match as well.
Too early to say anything. Pakistan got the initial advantage, when they won the toss and then decided to bat first. A lot will depend on how long Babar Azam stays out there. After these two, it is the allrounders and then the bowlers. Both the top-runs corers for Pakistan are out now (Mohammad Rizwan and Abdullah Shafique). Babar was in poor form until now, and it needs to be seen whether he will be able to rescue Pakistan today. So far both of them are looking somewhat comfortable against the spinners. But what will happen once Jansen and Coetzee are re-introduced?
In this world cup South African are completely different side with having impressive work against few teams which can create problems for the like England and Australia and currently Pakistan is also having serious trouble against them for having any good target which is looking not possible after this start. Jansen and Shamsi doing good job and Pakistan's problems are not allowing them to have anything positive from this world cup as with this performance look like today they will be face four lost in a row which could be another setback for them and their no 1 spot in ICC ranking.
Right now as they are losing matches I have feeling after this world cup many things are going to happen with on and off the field issues are waiting for them back at home and too many changes are also going to happen as well because all is not good well right now.
