More than Nawaz I would say Haider played very well. He went after Sodhi at a crucial juncture of the game. Because of his quick 31 in just 15 balls the game completely went in favour of Pakistan. This performance would help in the upcoming T20WC. Before this match he was struggling to score runs.
Today we have good entertaining end of this tri-series which won by Pakistan and all players done good job in this big match which was surely last test case for them before start of world cup and here we have to praise Nawaz and Haider as both done good job specially Haider's 15th over aggressive batting helps Pakistan to have win this match and cup with this performance now surely he can feel good because before start of world cup performance like this is surely having positive change in the team and players mind.
Nawaz is also having good time with bat and ball New Zealand is surely feeling not good but with their performance now we can give them good credit because they were completely out of touch in last few months, but they have done good job and have few players back in form which is surely going to help them in this event specially most chances they could be in semifinal with England as Australia is surely missing the magic.
