I don't know why people are blaming Pakistan middle order for giving their wickets. Had they batted patiently and taken a lead of 140, would that be better? No. I think on this wicket you have to score while you are at the crease. So Umar, Kamran, Yousuf did the right thing and now we have a 200 run lead which given Pakistan's batting line-up is a big big thing to have. I thought Pakistan will be all out for 220. They are 331-9 which is way too good.
Take Kamran out of the list. Scoring fast does not mean throw your wicket away or gift it to bowlers.
