Reason Why Pakistan Lost the Series

This trophy was just a 'decision' away. 

Sometimes cricket captains (especially Pakistani captains) make such strange decisions that even intellect and logic are stunned.  And sometimes it happens that luck helps people forget the decision in the joy of the result.

Everything was going well for Pakistan in the semi-finals of the T20 World Cup 2009 but captain Younis Khan suddenly gave over to part-time bowler Fawad Alam.  Seventeen runs were scored in this one over which could have been very expensive if the target on the scoreboard had not been so strong.
Pakistan was bowling the fourth innings in a Test match in South Africa.  Saeed Ajmal's tricks were not being played by any batsman.  Muhammad Hafeez wanted to bowl but Misbah-ul-Haq reversed the decision and Pakistan lost the match by four wickets.
There was a similar case here.  The pace on the wicket was not suitable at all and the spinners were setting the pace of the match from the first power play.  Adil Rashid inflicted the initial damage on Pakistan and then Moin Ali remained unbeaten in the middle overs.

Babar Azam also fed three spinners in terms of wickets.  Mohammad Hafeez's services were like a bonus.  If the captain has 16 overs of spin on such a slow wicket, what more does he need?
The scorecard collection was meager, but it was certainly defensible in the presence of four such spinners.

The kind of pitches we have seen in the last two matches, it was completely different from them.  The ball was stopping at the wicket.  Some balls bounce less, some more.  These were such precise conditions for batting that Mohammad Rizwan could not do as he pleased despite playing the entire twenty overs.

Babar Azam only had to decide how to divide the remaining four overs except for the 16 overs of a spin into pacers.  The turn in the wicket was from the beginning, but in the death overs in front of the old ball, it was impossible to think of power-hitting here.  This helplessness was evident in the short innings of Leung Stone, the best batsman of the last two matches.

The point is that when Shadab Khan on one side and Mohammad Hafeez on the other side had tied the English batting perfectly, why did Babar Azam suddenly feel the urge to attack with a piece?  The mystery is why Babar Azam did not go for Shadab Khan instead of Hassan Ali despite seeing the end of the pace in the 18th over.

There is no doubt that Hassan Ali is the best bowling bowler of death overs.  He has a lot of balls in his pocket, including slow balls, yorkers, and cutters, but this wicket was not only for him, it was not suitable for any pacer.  Of course, Babar had to pick them to bowl the last over.

But not stopping Shadab Khan in the 18th over was Babar Azam's minor mistake that snatched victory from Pakistan.  If Babar Azam had given that over spin, this whole story would have been different.

Pakistan could have won the match by four or five runs.  Either Mohammad Rizwan or Mohammad Hafeez would be called the Player of the Match and the trophy of the series would be taken by Babar Azam and his teammates.  But this seemingly trivial decision snatched a certain trophy from Pakistan's mouth.
