We shouldn't let his two fluke wickets at the end distract from the fact that his first over was probably the turning point of the run-chase for England and Harry Brook. Prior to him coming on to bowl England had just lost a wicket in the previous over and were well behind the scoring rate. Enter Mohammad Nawaz - who comes in, bowls absolute rubbish and goes for 17 runs in the last over of the powerplay. And from that point on, Brook never looked back.
In a match like this when you are defending a below par total, bowling a 17 run over right after a wicket fell in the previous over is a war crime. Nawaz should be sent to whatever is the cricketing equivalent of The Hague.
